Seven and one-half acres of floor space devoted to the manufacture 
of metal products shown in this catalogue 


in design, cost and use became in a few years the recognized standard 

for industrial buildings, is generally known. Steel sash brought higher 
standards of natural ventilation and daylighting, and made possible the 
newer types of industrial buildings and the use of larger floor areas for close 
association of manufacturing processes with consequent reduced production 
cost and improved workmanship. 


Cle development of solid steel sash, which by meeting every demand 


In this development, David Lupton’s Sons Company is recognized as the 
pioneer and leader, originating better types of steel sash and developing new 
and radically different methods for using them. 


Lupton Steel Windows for Commercial, Institutional and Resi- 
dential buildings are the next step! 


This is a logical development because architects, engineers, and owners 
fully recognize the greater economy, safety, and usefulness of solid steel sash; 
and the growing scarcity and declining quality of other window materials 
urge the adoption of steel. 


We have anticipated this by developing and testing, in actual installa- 
tions for each kind of non-industrial building, a Lupton window satisfac- 
tory in construction, sash movement and cost, and in its relation to all 
features of the design and use of the building. 

These Lupton Windows include similar types in two general classes, as 
follows: 


First—Casements, including the projected movement as well as the usual 
hinged and pivoted types; Double Hung Windows of entirely original con- 
struction assuring permanent tightness. These windows have welded 
assembly, fine finish and appropriate bronze hardware to meet the exacting 
requirements of monumental buildings, larger banks, hotels, office buildings, 
and fine residences. By standardized manufacture their cost has been 
reduced without impairing quality or finish. 

Second—Several types of sash of low cost, constructed to meet the needs 
of schools, small banks, hotels, offices, apartments, and residences. These 
types have all the features belonging to good steel sash construction. In 
addition, they have the ventilator movement, glass arrangement and _ hard- 
ware best suited to the buildings for which they are designed. They permit 
the unobstructed use of shades, screens and awnings, so essential in residences, 
schools, hospitals and offices.

LUPTON SERVICE 


Commercial Engineering, as applied to the design and use of equipment, electrical 
apparatus and machinery, has long been considered as the prime factor of their invention, 


development and economical use. 


It is applied knowledge of an industry, acquired through research, study and experience 
and embraces not only the products, their use, economical production and improvement 
but extends to their application for most satisfactory service, to the design of the build- 
ings in which they are to be installed and to the development or invention of new pro- 


ducts to meet new conditions. 


We were first to recognize that the future market for steel sash products depended on 
giving full investment value based on the use of the building. We applied commercial 
engineering to our industry, as shown in the standardization of our products, in economy, 
in production and maintenance, in the development of new types of sash and methods of 
control, also new building designs to meet requirements of various industries, so that 
good ventilation and daylight may be provided over unlimited floor areas. 


We produced the first solid steel counterbalanced, counterweighted and projected sash, 
also the first continuous sash and tension operator and introduced oxy-acetylene welding 
as a process of assembly of solid steel sash. 


Good sash do not necessarily make good buildings, unless the floor areas, roof-planes 
and sash types are in proper relation to manufacturing processes and the buildings are 
designed right for fresh air supply, ventilation and diffused daylight. 


Your factory and office employees will be healthy and contented when working in well 
lighted and naturally ventilated buildings, designs for which we can suggest to your 
architects or engineers when you are planning new buildings or remodeling old ones. Good 
working conditions reduce labor turn-over and promote that favorable attitude that is 
necessary to fine workmanship at minimum cost. 


Lupton Service is maintained to solve your problems in daylighting and natural venti- 
lation by indicating to you the most suitable types of sash and allied products to use, and 
their correct application; also by making constructive suggestions on the general layout 
and structural design of your building. There is no charge for this service. 


Lupton Service was developed by constant study of daylighting and natural ventilation 
where conditions can be positively determined owing to the smoke, gas or steam generated 
in manufacturing processes in foundries, forge shops, glass plants and similar industries. 
The principles determined by this study are applied with equal certainty to machine 
shops, textile mills, food processing plants and other industries where it is impossible to 
actually see the ventilating conditions. 


We recommend that an analysis based on the following principles be applied to your 
project in order to co-ordinate the manufacturing processes with the building design: 


6 


A—Primary material storage, material handling, sequence of manufacturing operations, 
and warehousing finished products are all studied and space for each process determined 
and located in economical relation to other processes and departments without limit of 
building types or dimensions. 


B—Having made the floor lay-outs that apparently will result in lowest storage, hand- 
ling and manufacturing cost, the building is then designed to meet all the mechanical and 
physical requirements. ‘This consideration of relation of processes will determine the use 
of a single or multiple story plant and establish the floor areas and all clearances including 
provision for mechanical equipment. 


C—The type of building having been decided upon, the roof planes, sash areas, types of 
sash and method of operation are all planned to produce the best result in natural venti- 
lation and daylighting throughout the floor areas. 


One story factories may be of unlimited length and width and have a number of pro- 
cesses generating heat, gas, smoke or steam without interfering with each other and have 
good light and ventilation throughout the entire area of the plant, if the Pond Roof System 
is used as recommended by us. On wide buildings it is necessary to have certain areas 
for fresh air supply, in which no heat generating process occurs. Application of these 
principles are shown in design chapter beginning page 8. 

We will make a personal analysis of the natural ventiJation and daylighting problems 
presented by your manufacturing processes and will furnish outline drawings for your new 
buildings or for remodeling old ones. These drawings will show the cross section, plan, 
and elevation, also roof and sash areas and the types of sash, percentage of ventilator 
opening and method of operation that as a composite whole will produce most satis- 
factory results. 

When plant extensions are necessary, it is often more economical to erect a new build- 
ing for special use and remodel the vacated buildings for ordinary use by changing roof 
and sash areas, than to entirely rebuild. 


Buildings can be remodeled at minimum expense and be very satisfactory for machine 
shop and other ordinary occupancy. 


Lupton Service is solely to assist architects and engineers as briefly outlined above, and 
your inquiries will be appreciated. 


DESIGNING FOR LIGHT AND 
VENTILATION 


In nearly every building, the efficiency of both lighting and ventilation depends on the 
sash. With the huge floor areas and carefully-planned layouts of today, it is true as never 


before that ‘‘the sash makes the factory.” 


Lupton Steel Sash Products are made for every industrial need. However, to get the 
best results, it is necessary for the buildings to conform to the characteristics of the sash. 
This applies not only to opening dimensions and attachments, but to placement of the 
sash, its operation, arrangement of roof planes to create natural air currents, and the 
proportion between ceiling height and width. Frequently it requires a definite relation 
between roof design and floor layout, since by placing the heat-producing processes correctly 


the desired air movement follows. 


Our experience has shown that the best 
results are obtained by observing the prin- 
ciples stated below. 


Multi-Story Buildings 

The least permissible light, and the angle 
of the sky line outside, determine the relation 
of floor width to ceiling height. Usually the 
storage and primary processes can be located 
on the lower floors, thus giving the upper 
floors to the finer work. 

Where many workers are employed, or 
where heat or fumes are produced, abundant 
ventilation is needed. To get the needed air 
change over a wide floor, top and bottom 
openings are required; and these should be 
close to the ceiling and floor. To make sure 
that the top openings shall actually be opened, 
it is best to connect them to the lower open- 
ings. With counterbalanced sash this is 
inherent in the design. With pivoted sash 
it is accomplished by connecting upper and 
lower ventilators by double arms. 

Where heat or fumes require exceptional 
ventilation, a very effective method is to use 
Pond Continuous Sash in upper and lower 
lines, with one operator controlling both 
simultaneously. An example is the Firestone 
Tire and Rubber Company Plant No. 2, shown 
on page 77. 

Another good plan is to run a line of Pond 
Continuous Sash above the regular windows. 
Ventilation will then be determined by the 


Sheet metal factory forming hollow rectangle, two stories high 
in center. Lupton Pivoted, Counterbalanced and Counter- 
weighted Sash are used, with Pond Continuous Sash in roof.

inlets. If a sufficient number of these be open, 
a uniformly distributed air movement results, 
which changes the air throughout without 
unpleasant drafts. 


Using the Roof for Light and Air 


With the roof available, opportunities for 
both daylighting and ventilation are vastly 
increased. This is true both of top floors and 
of wide single-story buildings. The roof is 
the best source of light, since the openings

lower ventilators, used in electrical factory.

are mostly above the line of vision, hence do 
not (except with a purely one-direction light) 
create unpleasant glare. Further, an over- 
head light casts small shadows; and with 
several properly-placed openings shadows are 
almost eliminated. 

Sawtooth 

Roofs 
For general use they are much inferior to the 
Pond Truss roof. 

A sawtooth roof gives a one-direction light, 
with little crossing of rays except by reflec- 
tion. If the floor beneath be crowded with 
dark machinery or goods, the workers must 
face away from the sash in order to see their

work clearly. 

On a wide building the sawtooth does not 
ventilate satisfactorily, because the side wall 
ventilators cannot admit enough air and the 
uniform height of the roof openings does not 
tend to create in-and-out air currents. One 
rarely finds a large sawtooth-roofed factory, 
unprovided with forced ventilation, in which 
the air does not always smell stale. 

If sawtooth must be used, Pond Continuous 
Sash with a 30-degree slope gives much more 
light than vertical sash, with full weather 


protection. 
Monitor These are of several types; 
Roofs the wide, flat-roofed monitor 


is best, and the old-fashioned narrow, peak- 
roofed monitor is worst. The old type ad- 
mitted very little light; its openings were 
inadequate and badly placed to receive heat 
currents; and cross winds could enter unim- 
peded, retarding the outflow and causing 
down drafts. 

The wide monitor gives a good light dis- 
tribution; and for buildings of moderate width, 
where no heat is produced, it ventilates fairly 
well provided the outlets are sufficient in size 
and hung with effective weather-protecting 
sash. It is not satisfactory for heat-producing 
buildings, or for very wide buildings; and a 
succession of small parallel monitors in a wide 
roof does not yentilate for the same reason 


DESIGNING, (FOR “LIGHT JA NIDaw E Net LAO 


. that a sawtooth roof does not. For all such 
buildings the Pond Truss is the best solution. 


Pond A- This is the simplest form of 

Frame weather-protected roof open- 
ing. While it gives the best results only under 
certain conditions, it is both effective and 
economical within its limits. It is an ideal 
means of admitting light and air through low 
portions of a roof between parallel Pond 
Trusses; and it is excellent for light courts. 

On top floors of narrow buildings a Pond 
A-frame gives better distributed light than 
a sawtooth, plus a choice of sash lines, either 
of which may be opened. 

A wide building such as a warehouse, re- 
quiring but little light and air, can use several 
A-frames at much less cost than either saw- 
tooth or monitors, and with better results. 


Pond For all other buildings requir- 

Truss ing ample light andeain 
whether wide multi-story buildings where 
best use of the top floor is desired, or large 
one-story buildings like machine shops and 
textile mills, the Pond Truss has been found 
the most efficient roof, both for daylighting 
and for discharging stale air and heat. 


Some typical Pond Truss cross sections are 
shown in the center insert, and photographs 
of these and other buildings are shown on 
pages 104 to 111. The characteristic features 
are the inverted or V-shaped roof and the 
combination of vertical and sloping sash in 
the sides. 


The raised portion is both wider and higher — 


than the old-fashioned monitor. Horizontal 
entering rays are reflected downward. Slant- 
ing rays from both walls and roof cross each 
other, producing not only a splendid illumina- 
tion over the central area, but also a practical 
absence of shadows. In a foundry with Pond 
Truss roof the molders can readily see the 
interiors of their molds. There is no glare, 
because even when facing the sash there is an 


equal “back light.” 


Where the ground plan permits, it is best 
to have the Pond Truss run north and south. 
This admits minimum direct sunlight at mid- 
day, but makes full use of the low-intensity 
morning and evening rays, which with other 
roofs are largely wasted. Compared with the 
sawtooth, a Pond Truss building adds from 


one to two hours of daylight at each end of 
the day. 


Owing to the better diffusion of light, and 
to the fact that the workers nowhere face 
harsh contrasts between light overhead and 
dark sides of work beneath, a Pond Truss 
roof may contain less glass than a sawtooth 
and yet give markedly better illumination. 
This saves heat as well as electricity. 

The ventilation produced by the Pond 
Truss is as effective as its lighting. Its out- 
lets are large in area, and are located to receive 


Pond A-frame and Lupton Rolled Steel Skylight over court of 
automobile factory. Lupton Counterbalanced Sash in walls 
give balanced in-and-out air movement.

dows, with line or group operation by Pond 
Operating Device. In summer, of course, all 
the sash or ventilators are open. In winter

36. All wall opening dimensions shown on plans 
are to follow the nominal dimensions of the sash, as 
shown in the details, diagrams of unit sizes, and 
table of combination widths, pages 28 to 37. Except 


as otherwise specified, walls are to be built before 
sash are set.) 


Opening Dimensions. The dimensions con- 
form to sash manufacturer’s standards, 
and are to be followed by the masonry 
contractor without deviation. Details for 
attachment of sash are likewise shown on 
plans and must be carefully followed. 
Jambs. In openings for multiple units in 
brick walls, the masonry contractor shall 
leave a groove or open Joint, 36” wide and 
114" deep in the first (or other as shown 
on drawings) joint from outer face of 
wall. (Detail 31.) This open joint shall 
be plumb and true and free from mortar 
and other obstruction. In concrete jambs, 
a similar groove, not less than 114” wide 
by 2" deep, shall be located to correspond 
with the groove in brick jambs.” (Detail 
27.) Where single units of sash are used 
in brick or tile walls, 

they may be set 

while walls are being 


built; or one jamb may be left unfinished 
till unit is inserted; or reveals may be 
used with clips (by Lupton) and anchor 
bolts (by others: see Detail 70); or the 
corners of the inner bricks at the grooves 
may be chipped to give clearance to insert 
the sash (Detail 11). 

Lintels. In brick walls, a structural steel 
lintel shall be furnished by the steel 
contractor, this member to provide a 
bearing for the sash. (Details g and 15.) 
If sill is to be pre-cast concrete, terra 
cotta, or cut stone, the. lintel must 
permit sash to be raised to clear sill 
before being lowered in place on the 
sill. In concrete walls a groove is to be 
cast in lintel not less than 114” wide by 
2” deep, in line with grooves in jambs. 
(Detail 28.) Lintels must carry their 
load without deflecting on sash, and have 
proper provision for receiving sash. 

Sills. Pre-cast, terra cotta or cut stone 
sills shall be set before sash are installed 
and shall contain recesses not less than 
2 inches deep to receive the lower ends 
of the mullion stems. (Details 43 and 
25.) Brick and poured sills shall be left 
unfinished till sash have been erected.

Lupton Pivoted Sash 


(Patented and Patents Pending) 


Lupton Pivoted Sash is the most economical type of steel sash manufactured. It is 
used in the walls of buildings for all kinds of industries where abundant daylight and 
good ventilation at low cost are required. Its narrow lines offer minimum obstruction to 
light, and it is not subject to the warping and sticking that often render wood sash 
useless for ventilation. The modern daylight, fresh-air factory, containing sometimes 
many acres of floor space, owes its existence, more than anything else, to the large glass 
areas and ventilating openings made possible by this and other types of steel sash, and 
to the fact that pivoted-ventilator steel windows cost less than masonry and its supports 
for the same wall area. 


While Lupton Pivoted Sash is primarily designed for individual control of ventilators, it 
may be used also where the ventilating conditions are exacting, the arrangement in this case 
being to connect groups of the ventilators (usually the upper ones) in long lines, and to open 
or close them simultaneously by mechanical operators. 


This arrangement is not advisable for roofs, owing to the ease with which rain enters 
between the ventilators, but it is much used in side walls where a reasonable degree of 
weather protection is sufficient. 


For complete weather protection in roofs and walls, Pond Continuous Sash should be used. 


Lupton Pivoted Sash, though sometimes used in non-industrial buildings such as offices 
and schools, is not recommended for that purpose. Lupton Projected, Counterbalanced, 
Counterweighted, Double Hung or Casement windows should be used for such buildings. 
See chapters or separate catalogues describing those types. 


The most-used sizes of Lupton Pivoted Sash are carried in warehouse stocks in Phila- 
delphia, Cleveland, Chicago, Detroit, Buffalo and Atlanta, and by a number of agents 
in other cities. This permits most orders to be shipped immediately. Large orders are 
best made up from the pre-cut bars which are kept constantly in stock at the factory. 
See page 18 for the distinction between Warehouse Stock, Standard, and Special Sash. 


Not only is Lupton Pivoted Sash the most economical type for large industrial buildings, 
but it is rapidly displacing wood in small factories, shops, warehouses, private garages and 
the like. Not only does its first cost, including erection, compare favorably with that of well- 
made wood windows, but the subsequent comparison is wholly in favor of steel. Lupton 
Pivoted Sash does not swell, shrink or warp. It is free from the progressive deterioration 
and sensitiveness to rough usage that characterize wood; and the narrow steel surfaces 
require less paint. .It lends itself much better than wood to large glass areas. 


In case of fire, Lupton Pivoted Sash does not add to the flames. Since only a few changes 
are required to convert Lupton Pivoted Sash into Underwriters’ Sash, the same type of win- 
dow can be used for external fire hazard as elsewhere. 

Sizes and methods of attachment to all kinds of walls are standardized, and full 
particulars are given in the following pages. While it is advisable for us to erect the sash 
on large orders, a small order can readily be erected by the brick mason or carpenter. It is 
not necessary to bea steel sash expert, if our instructions are carefully followed.

SASH 


Construction 

All members are of low carbon steel, specially 
rolled for us in solid one-piece sections designed 
for necessary strength without needless weight. 

Frame members and muntins are assem- 
bled with flush joints. The intersection of the 
muntins is illustrated on this page. The 
design of the interlock combines most effective 
placing of metal with least practical deforma- 
tion, and its ample strength against both wind 
pressure and wind suction has been fully 
demonstrated. The greater the external 
pressure, the tighter is the lock of the inter- 
secting members. In addition, the Lupton 
joint gives the least opportunity for moisture 
to enter and cause corrosion. 


The ends of the muntins and the corner 
joints of the frame members are riveted. 


All Warehouse Stock and Standard Sash 
use angle section 308 as the frame member. 
This member makes attachment extremely 
simple, and gives maximum strength in brick 
and concrete, because it has a continuous 
bearing in the wall. It should be used in all 
cases, even when the sash is otherwise special. 


Exact fit of every member is guaranteed by 
using large presses and gang punches, which cut 
the ends, notches and slots simultaneously in 
one operation for all standard bars. Special bars 
longer than 13 feet are cut in two operations. 

This simultaneous punching applies to all 
members wherever used. It is a complete 
insurance against faults in size, also against 
faulty ventilator alignment. Since even the 
hinges of Lupton Pivoted Sash are integral 
with the weathering, a ventilator can fail to 
fit only through twisting or bending, which is 


easily corrected. 


Ventilators 


Ventilators make a 2-point contact all 
around, the enclosed air space minimizing 
air leakage. 


The weather-tightness of a pivoted ventila- 


16 


tor depends on the accuracy of its fit. By 
making the hinges integral with the structure 
of the ventilator and sash, and cutting all 
bars to exact measure in gang dies, this 
primary cause of error is removed. If the 
ventilators do not fit when the sash are set 
in the walls, it is because some member has been 
sprung in transit or handling; and by springing 
it back the original fit is restored. 


Ventilators in Warehouse Stock and Stand- 
ard Sash are pivoted 2 inches above center. 
The hinges are integral with the weathering

sag. A continuous weathering is maintained 
when the ventilator is closed. 


The Lupton Stay Bar deserves special notice 
for its strength and simplicity, and for the 
secure lock it affords. It is an angle bar, 
suitably notched and folding back against the 
sash when closed. Because of its shape it is 
much stronger than a flat bar. An embossed

fulcrum point in the stay bar, bearing against 
the sash, ensures tight closing. 


At the option of the purchaser, ventilators 
are provided with stay bar operators; or with 
spring catches and chains. The price for 
sill-length chains is the same as for stay bars. 
Unless otherwise specified, we furnish stay 
bars for all ventilators except the upper one 
of a pair, and spring catches and chains for 
upper ventilators. It is ‘safest, however, to 
specify operators desired. For windows with 
high sills, we furnish a special chain clip, 
No. EL-2365, to be fastened to the wall below 


the sill. 


If desired, Pond or Lupton Operating 
Device may be added to control the venti- 
lators in lines or groups. 


The locations and sizes of ventilators in 
Warehouse Stock and Standard Sash are shown . 
on pages 28 and 2g. Any departure from these 
comes under the head of Special Sash and must . 
be made to order at an extra charge. 


Where window cleaners’ anchors are ordered, 
those made by the National Safety Device 
Co., 153 North La Salle St., Chicago, will be 
furnished unless others are specified. 


Mullions 


The T-bar mullions, Sections 121 and 3395 
are invariably furnished where mullions are 
required. They are attached 
outside thesash, withstems pro- 
jecting either inward or out- 
ward. See table, page 30, for 
limit heights of these mullions; 
also for details showing placing 
of mullions and their length 
when cut. 


The jamb members (Section 
308) of all sash are punched 
with horizontally slotted holes. 
The mullions have vertically 
slotted holes. This facilitates 
erecting and leveling the sash.

Paint and Shipping 


Lupton Pivoted Sash are given one shop coat 
of paint, oven dried, and are furnished with 
stay bars or spring catches for ventilators, also 
Lupton Glazing Clips and standard wall ties. 
Mullions and mullion bolts are included when 
specified. We do not furnish expansion bolts. 
See under “Information to be Included with 
Order” for items necessary in specifications. 


Spring catches and stay bars are shipped 


separately from the sash in order to avoid 
breakage in shipment or erection. 


They are 
easily and quickly attached by any mechanic. 


Stacking 
Lupton Steel Sash should be carefully 


stacked as soon as received, by standing them 
on edge on three or more level pieces of lum- 
ber, such as 3 x 4’s, with strongly braced up- 
rights against which the sash may lean. Do 
not lay sash flat or pile one upon another. 


Warehouse Stock, Standard and Special Sash | 


Warehouse Stock Sash are the most used 
sizes of stationary and pivoted sash in 12 by 
18 and 14 by 20 inch glass sizes. They are 
strictly standard in construction, and are 
carried, fully manufactured and ready for ship- 
ment, in our Philadelphia, Cleveland, Chicago, 
Detroit, Atlanta, Buffalo and agency ware- 
houses. They are shown shaded on pages 28 
and 29. 


Standard Sash include all those sizes and 
ventilator arrangements in common use. hey 
are not assembled in advance, but large 
stocks of the cut bars are always carried in 
our factory, ready for quick assembly. 


Warehouse Stock Sash should always be 
used where possible, in preference to Standard 
but non-stock sizes. They cost no more, and 
the quicker delivery is often very important. 
Even if the entire building cannot be supplied 
from stock sizes, most of it usually can; and 
this frequently permits the 
work to progress while the non- 


stock sizes are being made up.-

the description compared with the list below, to 
see that it is complete. 


1. Shipping date desired (on non-stock sizes,

7. Height of sills from floor. This tells 
us, first, the proper length of chains 
when chains are required; second,whether 
the lower ventilator should be operated 
by chain or stay bar. 


Where sill height is not specified, we supply stay 
bars with all single ventilators, also with the lower 
ventilators of pairs. Spring catches and chains are 
furnished with upper ventilators of pairs. Where 
sill height is specified, we furnish spring catches and 
chains only for ventilators whose bottom edges are 
more than 6 feet above the floor. If for any reason 
stay bars are wanted on high windows, or chain 
catches on low windows, that fact must be noted 


in the order. 


8. Kind of wall fastenings required. 
This depends on the construction of 


the walls—whether brick, concrete, stone 
or steel; also on the method of attach- 
ing sash. It is necessary to give attach-

jambs in concrete, or at jambs in brick (except 
for detail No. 70). No. EL-435 standard clips for 
angle lintels (see detail 12, page 32), and No. EL- 
1739 standard anchor ties for sills (see details 17 and 
43, page 35), are regularly furnished. If clips 
are required for jambs also, they should be speci- 
fied in the inquiry and order. Bolts and washers 
are furnished with mullions. Sill angle clips shown in 
details 79 and 89, pages 32-33, are special, and are 
furnished only when specified. 


Symbols Used When Ordering Sash 


Initial letter shows glass size: A, 10 x 16 
in. B, 12 x 18 in.; C; 14.x 20 in.; 19,16 x22 in. 

First numeral—number of lights wide. 

Second numeral—number of lights high. 

Third numeral—number of ventilators. 

Fourth numeral—number of lights per 
ventilator. . 

Fifth numeral (after dash)—number of 
stationary lights high between bottom of 
sash and bottom of ventilator. 

Sixth numeral (after second dash)—num- 
ber of stationary lights high between lower 
and upper ventilator. 

Examples: C56 means a unit taking 
14 x 20 inch glass, 5 lights wide, 6 lights high, 
stationary. C4g518-1 is a sash taking 14 x 20 


inch glass, 4 lights wide, 5 lights high, having 
one 8-light ventilator, one light above bottom 
of sash. Cs626-1-1 is a sash § lights wide, 
6 lights high, having two 6-light ventilators; 
the lower ventilator one light above the 
bottom of sash, and the upper, one light above 
lower. 


Indicate the number of sash units in each 
wall opening, by writing such number before 
the sash symbol. For example, 2 openings — 
3/B4618-1 means that for each of two open- 
ings three units are required of the sash 
symbol given. Consequently two mullion 
bars are needed for each opening. Sometimes 
units of different widths, or having different 
ventilators, are used to fill an opening. For 


example, 2/C36; 2/C5616-1; 1/C4618-3. 


Designing the Walls 


The details on pages 32 to 36 show the com- 
monly used methods of arranging wall open- 
ings to receive Lupton Standard Pivoted Sash. 
Opening sizes are identical with the nominal 
sash sizes. Where several sash units occur in 
an opening, two inches are added for the width 
of each standard T-bar mullion. 


20 


Standard mullions do not attach to the 
head or lintel. Their stems extend into brick 
or concrete sills 2 inches below the measuring 
line of the sash. Recesses must be provided 
in the sills to receive the mullions, if the sills 
are set before the sash are erected. 

Standard mullions are always attached with 


usr Oweee ey ODED SASH 


the flanges of the T-bars outside of the sash 
frame members. In brick and concrete walls, 
the stems may project either inside or out- 
side, according to the wind pressure they 
are required to sustain. (See page 30.) In 
steel framing the stem must always project 


outside. (See detail 5, page 32.) 


Sash are secured by bolts, clips or grout. 
The frame members are punched at the sides 
for mullion bolts, and at the sills for wall 
anchors. Standard clips and wall anchors 


(page 23), should be used where possible. 


If but one unit of sash is used 1n an opening 
in a brick or concrete wall, special provision 


is necessary to insert the sash. See under 


“Building the Walls,” below. 


With all kinds of steel sash, it is essential 
that the structural steel lintels or other sup- 
porting members shall carry their load without 
deflecting upon the sash, as that would cause 
the ventilators to bind. 


A special case arises in brick and concrete 
walls where sash have full-width upper and 
lower ventilators connected by double arms. To 
give clearance for the arms, the jambs must 
have a reveal (details 70 and 8, pages 34-35), 
or a-special jamb plate (detail 26). Otherwise it 
is necessary for the end units of sash to have 
stationary lights adjoining the jambs. 


Building the Walls 


Steel sash are built to support glass and to 
withstand wind pressure after they are properly 
placed in the walls. They are not built to 
endure miscellaneous rough handling, or to 


hold bricks and lintels in place. 


We recommend that walls be built before sash 
are set. This applies to all types of construc- 
tion, except sometimes in brick walls where but 
one sash unit per opening is used. See under 


“Brick Walls,” below. 


Brick Walls: Standard practice is shown in 
details 9, 14 and 31, page 34. Brick sills and 
poured-in-place concrete sills should not be set 
till sash are erected. Jambs of multiple open- 
ings should have a vertical groove 34 inch wide, 
11% inches deep, raked out of the mortar by the 
mason, when laying the brick joint. 


Openings taking but one sash unit must 
have one jamb left unfinished until the sash 
are set. Alternative constructions are to 
make each jamb with a reveal (See detail 70), 
or to chip the bricks in each jamb so that 
one side of the sash can be inserted and the 
other side swung into place. (See detail 
Wie) lesdetater Tissused, it aisenecessary, to 


iM 


provide extra clearance at head or sill, 
to avoid interference with the sash when the 
latter is inserted. This can be done by making 


a low sill, and filling with grout under sash. 


The lintels may be structural steel members, 
with a continuous plate, angle, or %@ inch 
groove for attaching sash. (See details 80 
and 9.) 

Where pre-cast, terra cotta or cut stone sills 
are used, the lintel must allow sash to clear 
sill before being placed in final position. (See 
detail 80, page 33-) Mullion stems must enter 
recesses or joints in sill. 


Concrete Walls: Grooves not less than 
114 inches wide, 2 inches deep, are moulded 


in jambs and lintel. (See page 35.) 


When but one sash unit is used in an open- 
ing, grooves in the lintel and one jamb must 
be larger as required to insert the sash; or 
(See 


the jambs must be made with a reveal. 


detail 8.) 


Poured-in-place sills are recommended. If 
pre-cast or cut stone sills are used, the groove 
at head must be deep enough to allow sash 


to be lifted clear of sill before being set.

Steel Framing: Either of two treatments 
may be used at the head. The first is to

two channels back to back, with spreaders 
between them, making a 38 inch space to 
receive the heads of the sash. (See detail 15, 
page 33.) For the jambs and sills, angle or 
channel bars are used, with clips or straps 
to secure the sash. (See details on pages 32 to 
33-) The T-bar mullion is always placed out- 
side the sash, with stem projecting out. 


Wood Walls: The standard angle frame 
member, Section 308, may be attached to 
wood walls in a great variety of ways. Speci- 
men details are given on page 36. It is 
essential that the lintels shall carry their load 
without deflection against the sash. 


Erecting and Glazing the Sash 


Note: Hinges are above center of ventilators. 
Their position should be noted when placing 
sash. 


Brick Walls: The end sash units in each 
opening are first set with the flanges of frame 
members, Section 308,in the jamb grooves; then 
the remaining units with their mullions are set 
and loosely bolted; after which they are leveled 
and wedged against the jambs and head. The 
mullion bolts and the bolts or clips at the 
lintel are then tightened, and the jamb grooves 
and sill are grouted by the brick mason. Mul- 
lions are set with flanges outside of sash. 

If sills are left unfinished till sash are in 
place, the sash must be supported on wood 
blocks and wedges, which are set under corners 
of sash only, in order not to distort the sash. 

The head and jambs should be grouted after 
the sill has been finished. 

Single units in openings are treated accord- 
ing to the provision made to receive them: 


see under “Building the Walls,” 


above. 


Concrete Walls: 
as for brick walls, the grooves in concrete 


Same general procedure 


being grouted after sash are wedged. If there 
is but one unit per opening, it must be inserted 
in the larger jamb groove first. 

Steel Framing: The sash are attached by 
bolts or clips as shown on pages 32 and 33.

They are first loosely bolted and lined up by 
wedges, after which the bolts are tightened. 

The mullions must be set with the stems 
turned outside, and the flanges outside the 
sash. See horizontal section, page 31. 

Wood Framing: Use same general proce-_ 
dure as for steel framing, except that screws 
are used instead of clips. 5 

After Erection: Wires holding ventilators 
shut are removed and spring catches or stay 
bars attached. 

Glazing: Sash are glazed after erection: 
the work is done from the inside. The lights 
are held by the wire glazing clips shown on 
the next page, four being furnished for each 
light. They are sprung by hand into holes 
in the muntins and frame, and their elasticity 
permits the glass to expand without breakage. 

Glass should be carefully back puttied, and 
putty should also be applied inside and beveled. 

Special putty for steel sash should be used, 
as ordinary putty dries out and breaks away. 

When ordering glass it is important to note 
that border lights in ventilators are smaller 
than the other lights. See “Glass Sizes in 
Ventilators,” page 30. 

Painting: Sash are painted one coat at 
factory. They should receive at least two 
coats of paint after erection,

Lupton Underwriters’ Sash can be filled from 
bars in factory stock, subject only to the 
delay for adding the hardware. This is the 
most economical way to buy Underwriters’ 
Sash. Such orders can usually be filled within 
one week from receipt of complete information, 
but it is well to allow more time if possible. 

Where immediate delivery is essential, Ware- 
house Stock Sash can be altered at our Phila- 
delphia, Cleveland and Chicago warehouses, at 
a slight extra cost, to receive the special glazing 
angles and hardware before shipment. Sash 
cannot be altered to receive Underwriters’ Label 
after shipment. 


Following are the Underwriters’ Labora- 
tories’ specifications, in condensed form, so far 


as they apply to pivoted sash: 


1. No sash unit may exceed 7 by 12 ft. in 
size. (Either dimension may be width.) 
Dimensions are taken to the usual measur- 
ing lines. 


2. The exposed glass area must not exceed 
350 square inches in any light, measured 
from toe to toe of the glazing angles. 


ERS LABORA 


(Standard sizes are less than _ this.) 
One-quarter inch wire glass is always 
required. 


In addition to putty, the lights are held 
by steel glazing angles measuring %4 by

carried also completely assembled in warehouse 
stock. When so assembled, they are known as 
Warehouse Stock Sash. These sizes are shown

between Stock and Standard Sash, but the quicker 
delivery on the former is often important.

Special Lupton Pivoted Sash 


All sash departing in any particular from 
the foregoing specifications of Standard and 
Warehouse Stock Sash are classed as’ Special 
and require longer delivery and a_ higher 
price. Sash which have the same number 
and size of lights, but which have some require- 
ment not included in the Standard and Ware- 
house Stock Sash, are classed as Special. 
Examples are, the use of frame members other 
than Section 308; different size or location 
of ventilators; and different location of ven- 
tilator pivots. 

As such sash can be made only at an outlay 
of time for designing and for specially making 
up the various parts, it is desirable to use 
Standard and Warehouse Stock Sash wherever 
possible. 

Underwriters’ Sash in Standard sizes are 
not classed as Special. 

We will furnish, at an extra charge, double 


Glass Sizes 


The outside lights of all ventilators are reduced 
one inch in width or height, or both, to allow for 
the space taken by the weathering around the 
ventilators. See diagram, and bear in mind when 
ordering glass.

connecting arms for the simultaneous control 
of two ventilators in a sash unit. These arms 
attach to adjustable brackets so that the 
ventilators may be fitted to close tight with- 
out slamming. If upper and lower ventilators, 
the full width of the units, are connected by 
double arms, the jambs must have a reveal 
for clearance. 

It is recommended that ventilators not 
exceeding two lights in height be used. Single 
ventilators should not exceed five feet in 
either width or height, nor have an area greater 
than 18 square feet. 

To order Special Lupton Pivoted Sash, the 
same system of symbols is to be used as for 
Standard and Warehouse Stock Sash; see 
page 20. If the glass size desired is other than 
those indicated by the letters A, B, C or D, 
it should be stated specially.

Lupton Pivoted Sash with Pond Operating Device 


In power houses and other buildings where 
many ventilators require to be controlled 
simultaneously, we furnish Pond Operating 
Device for use in connection with Lupton 
Pivoted Sash. 

For a detailed description of Pond Operat- 
ing Device, see page 94. As applied to pivoted 
ventilators, it uses compound levers of special 
shape, which are bracketed on the sash. 

Where desired, upper and lower ventilators 
are connected by double arms, as shown on 


page 45. 


Owing to its low friction, the capacity of 
the Pond Operating Device is remarkable. 
In the Lake Street power house of the Cleve- 
land Electric Illuminating Co., 186 pivoted 
steel ventilators are controlled by a single 
hand chain and Pond Operating Device. In 
the Mississippi River Power Company’s plant 
at Keokuk, Iowa, there are 504 pivoted steel 
ventilators, all controlled simultaneously by 
Pond Operating Device, "sing one electric 
motor. 


The three views on this 
page show Pond Operating 
Device applied to Lupton 
Pivoted Sash. The com- 
pound levers are connected 
alternately to the upper 
and lower tension rods, so 
that both rods (moving op- 
posite ways) act on each 
ventilator. Thus the work 
is equally divided between 
the tension rods, and the 
lateral components of the 
thrust are neutralized for 
each individual ventilator.

Lupton Operating Device 


Lupton Operating Device is designed to 
operate small groups of pivoted ventilators 
(not more than 12 of average size by one oper- 
ator). It is moderate in cost, strong, simple 
to operate, and easy to erect. It works by 
torsion, and we consider it equal to any device 
of its kind for the service indicated. It 1s not 
suitable for long lines of sash, for which the 
tension principle embodied in Pond Operating 


Device has been proved correct. 


The 


Device consists of a cast iron worm, segment 


mechanism of Lupton Operating 
gear, torsion tube, lever arms, and sash rods 
acting on the. ventilators. The worm and 
segment are not machined or encased. Brack- 
ets are furnished for attachment to wood, 
brick or steel supports. The operating power 


may. be located so that the worm shaft is 


- each 40 feet. 


horizontal and turned by a hand chain, or 
vertical and turned by a hand wheel or pole 
hook from below. 


To secure satisfactory service from Lupton 
Operating Device, the torsion tube should not 
extend over 40 feet on either or both sides of 
the operating power, and should not operate 
more than 6 ventilators of ordinary size in 
Where upper and lower venti- 
Jators are operated in pairs, the torsion tube 
should not extend over 20 feet on either or 
both sides of the operating power, and should 
not operate more than 3 pairs of ventilators 
ineacn2o feet, 


When ordering, the following information 
must be clearly given. A free hand sketch or 
scale drawing is desirable:

ROW DesGOunsyINUOUS SASH 


Pond Continuous Sash 
(Patented and Patents Pending by Clarke P. Pond) 


The idea of a continuous, weather-protecting line of sash, hung in long unbroken lines 
outside of structural work, was first embodied in Pond Continuous Sash, made by this 


company. 
factory, La Salle, Ll. 


Its first application was in 1909, in a sawtooth roof of the Western Clock Co. 


Since that date Pond Continuous Sash has been applied in a great variety of ways in 
roofs and side walls, where it has accomplished ventilating results impossible with other 


types of sash. 


The purpose of Pond Continuous Sash is fourfold: 


Sawtooth roof with fourteen 70 foot lines of Pond Continuous 
Sash controlled by one electric motor. 


Pond Continuous Sash operated in groups in walls, and in 
long lines in monitor. 


Pond Continuous Sash used in connection with Lupton 
Counterbalanced Sash in a heat-producing building. 


1—To give protection from rain 
when open, 

2—To deflect winds over roof and 
avoid down draft, 

3—To afford mass control of 
ventilating openings, 

4—To give the largest effective 
opening area consistent with 
the first three features. 

These purposes are accomplished by 
hinging the sash at the top, and connecting 
it by waterproof joints into a continuous 
line. Thus it forms a transparent shed 
over the ventilating opening, which may 
be hundreds of feet long. The ends overlap 
stationary glass storm panels, which pre- 
vent rain entering at these points; and the 
details are carefully planned for exclusion 
of rain when open and for weather-tightness 
when closed. 

By avoiding the gaps between center- 
pivoted ventilators, top-hung Pond Con- 
tinuous Sash permits ventilation in all 
weathers. It need never be shut save for 
warmth. It is also inherently closer fitting 
when shut than any center-pivoted con- 
tinuous sash can be. 

Using Pond Operating Device, up to 1000 
square feet of sloping sash, or 2000 square 
feet of vertical sash may be controlled 
through one hand chain. With electric 
motors the areas may be much greater, 
permitting all the sash in a large building 
to be opened or closed in a few moments.

Though originally designed for roofs, Pond Continuous Sash is equally useful for side- 
walls, where it may be used either as an outlet in multi-story buildings, or as a continuous 
inlet, permitting slow diffusion of fresh air without local drafts and consequent liability 
to colds. 


Its most effective use is in connection with the Pond Truss roof and Pond A-frames. 


Through its combined weather protection and mass control, Pond Continuous Sash has 
profoundly influenced the design of industrial buildings, permitting them to be made 
larger and at the same time more hygienic and pleasanter to work in. Extremely wide 
and long structures may be used, which heretofore have been impracticable owing to in- 
ability to daylight and ventilate them properly. Such areas under a single roof permit 
more intensive co-ordination of processes 
and handling, resulting in marked econo- 
mies in production. 


Below are listed the commoner roof and 
wall constructions in which Pond Con- 
tinuous Sash is used to advantage. For 
a discussion of their best uses see pages

Sawtooth Roofs. While this form of Pond A-frame hung with Pond Continuous Sash. 
roof is much less highly esteemed today 
than it was some years ago, Pond Continu- 
ous Sash enables it to show the best results 
of which it is capable. With that sash it is 
not necessary to interrupt ventilation during 
a rain in order to protect goods and equip- 
ment. Owing to its effective protection 
and easy control, Pond Continuous Sash 
is best used on a 30 degree slope, thereby 
admitting about 50 per cent more light 
for equal glass area than vertical sash 


would give. 7 : :

Monitor Roofs. Pond Continuous bunker. Pond A-frame is seen at right. 
Sash is valuable in all roofs of this type, . 
enabling full production to go on in any 
weather. Long runs of sash are preferable. 
Best results in both lighting and ventilation 
are had with fairly wide, flat-roofed moni- 
tors in narrow buildings. In buildings of 
medium or greater width, the Pond Truss 
gives much more effective ventilation and 
better light diffusion.

and slope of its roof planes carry rising air currents directly to large outlets hung 
with Pond Continuous Sash in long lines. These outlets cross-light the area beneath, 
giving abundant, almost shadowless illumination. “Spotty” ventilation is avoided by 
uniform openings and by having part, at least, of the sash in the side walls mass-controlled 
by Pond Operating Device, so that inflow as well as outflow is uniformly distributed. 


By filling the entire side walls with Pond Continuous Sash and making the outlet areas 
equal to the inlets, heat-producing buildings as much as 250 feet wide can be effectively 
ventilated with but a single wide Pond Truss. 


Pond A-frame. Pond A-frames are best used to admit fresh air and light through low 
roof sections between Pond Trusses. They are useful also for local daylighting, and 
sometimes as ventilating outlets. For the 
latter purpose they are equivalent to narrow 
monitors at less cost. They are superior to 
skylights for court light and ventilation. 
See chapter on Designing for Light and 
Ventilation, pages 8 to 11, for a further 
discussion of their uses. 


Boiler Houses. Any firing aisle can be 
made comfortable and well lighted by prop- 
erly designing the roof and using Pond 
Continuous Sash to discharge the surplus 
heat above the boilers. See page 91. 


Side Walls. In Pond Truss foundries 
and forge shops a large inflow is obtained 
by using Pond Continuous Sash in the 
upper side walls. By admitting fresh air 
along the entire length of wall, and allow- 
ing it to diffuse before reaching the floor, 
local drafts and colds are avoided. 


The same principle applies to buildings 
for any purpose involving heat, fumes or 
gases. The sash may be run in long lines 
outside of columns, or in short lengths 
between pilasters, several lengths being 
control ed by one operating “‘power.”’ 


A special form of Pond Continuous Sash 
is made for power house walls. See pages 
S3e.tO: Ot.

at all edges when closed, and is furnished 
either with or without imposts and mullions

SASH 


General Construction 

Pond Continuous Sash is made in standard 
units 3, 4, § and 6 ft. high, and 20 ft. long. 
To fill out ends of runs, units 10, 12, 14, 16 
and 18 ft. long are used as needed. Each end 
unit in an operated line overlaps a stationary 
storm panel 2 feet wide. At the head, the 
sash are hinged under a continuous angle girt 
which prevents rain from entering at the top; 
and a similar girt forms the sill. Sash units 
are connected by integral expansion joints 
of special design, combining flexibility with 
least practicable air leakage. 

All joints of sash are solidly oxy-acetylene 
welded. The bottom rail of the sash is of 
patented shape, giving maximum rigidity. 

The standard and end units above named, 
also storm panels and operators, are carried 
in stock in our principal warehouses. 


Members 
These are one-piece sections, and are shown 
full size on page 62.. They are unusually sub- 
stantial, and this extra strength is well justi- 
fied by the resulting economy in maintenance. 


The bottom rail receives the thrust of the 
sash rods. It is specially rolled, and it 
avoids the faults inherent in Z-bar and simi- 
lar forms when used for this purpose. Since 
the wings are placed opposite, there is no 
tendency to twist and start leaks or glass 
cracks. Drip holes in the outer wing allow 
water to escape outside the building when 
the sash are open, without recourse to a filling 
of putty at this point to prevent corrosion. 
We have found that putty applied thus be- 
tween surfaces at right angles, and exposed 
to weather, soon breaks away owing to lack 
of a positive retaining hold. This does not 
happen with elastic bed putty, held and pro- 
tected between parallel surfaces of glass and 
Steer 

The hinges have bronze pins. They are 
bolted to the overhead girt angle and to the 


top rail of the sash. When the sash are closed 
the hinge action forces the top rail against 
the girt angle, minimizing air leakage at that 
point. This contact does not depend on a 
continuous bearing, which is of little value 
when the steelwork is not in perfect alignment 
with the sash. 

The bottom rail laps the girt angle forming 
the sill, and is pulled up against it by the 
operating device, which is adjusted for that

purpose during erection to compensate for 
unavoidable variations in sill alignment. Bot- 
tom rails of stationary sash are fastened to 
the sill by strap clips bent over the steel work. 
Top rails are hinged as for operated sash. 


Welded Assembly 
The welds at the joints of Pond Continuous 
Sash are real welds. Each member, including 
the expansion cover, is welded to the attached 
members along their entire line of contact.

op 


Thus each unit becomes a single rigid piece; 
there is no possibility of the joints loosening 
later by racking or internal corrosion, with 
resultant glass breakage and cracked putty. 


This method of assembly is far more costly 
than riveting or spots of hot metal here and 
there. We use solid welds, not for our benefit, 
but for the customer’s. 


Storm Panels 


These are used with operated lines of Pond 
Continuous Sash in roofs, and with long 
operated runs in walls. Each storm panel is 
2 feet wide, underlapping the end light in the 
operated sash, and is built in one piece with 
a stationary end panel extending 2 feet beyond 
the sash. 


Stationary lines of Pond Continuous Sash 
are usually arranged to meet a short (2-ft.) 
end panel; the storm panel being omitted. 
When that is done, the end panels may readily 
be replaced later by combination storm panels 
if the line is changed to operated. In order 
to do this, however, it is necessary that the 
stationary sash be hung from an overhanging 
girt angle. 


Both the stationary end panels and the 
combination storm panels require flashing. 
See under “Flashings,” page 60. They are 
glazed in the same manner as Pond Continuous 
Sash: see under “Erection and Glazing,” 


page 58. 
Expansion Joints 


Expansion joints are necessary to long lines 
of continuous sash. Their function is to take 
care not only of unequal expansion, but— 
what is much more vital—of unavoidable 
inequalities in the steelwork. A certain degree 
of flexibility of the sash, both in its own plane 
and at right angles thereto, is necessary to 
avoid glass breakage and loosening of putty. 
This flexibility is destroyed when units are 
rigidly bolted together; and if the bolted 


POW-D: CONTE ENUO1U;S sess 


joints be located under the glass lights the 
slightest flexure there tends to break the glass. 

Joints between units of Pond Continuous 
Sash are so designed and located as to have 
all needed flexibility without the slightest 
strain on glass or putty. They give ample 
flexibility in doth planes. The joint cover is 
an integral part of one sash section; hence 
there is only one lap contact—with its chance 
of air leakage—instead of two, as would be 
the case with a loose cover. 

This is the most expensive form of expan- 
sion joint used in continuous sash. We use 
it because it assures to the customer the dura- 
bility, freedom from glass breakage, and 
absence of needless air and water leakage 
to which he is entitled in high grade sash. 


Pond Continuous Sash in Walls 


Pond Continuous Sash may be used in walls 
in two ways. The first is to use it as in roofs; 
i. e., in long continuous runs outside of steel- 
work. This construction is frequently used 
in foundries and similar buildings. When 
that is done, combination storm panels and 
short end panels are used as in roofs,—the 
former for operated lines, the latter (usually 
but not necessarily) for stationary lines. 

The second way is to use it in short 
lengths between pilasters, the lengths being 
connected in lines or groups for simultaneous 
control by Pond Operating Device. For that 
purpose stationary end panels are omitted, 
and the end rails are shaped to lap special 
plate weathering set into the masonry. This 
weathering must be carefully located in the 
plans and attached to the steelwork by the 
general contractor before the jambs are built. 

For Pond Continuous Sash in long runs 
standard units are always employed. For use 
between pilasters, special lengths can be fur- 
nished if necessary, with special glass widths 
but standard heights. 

For power house walls a special construction 
is used. See pages 83 to gI. 


Standard Dimensions 


Standard units of Pond Continuous Sash 
are 20 ft. long. Shorter lengths, 10, 12, 14, 
16 and 18 ft. long, are carried in stock and 
used at the ends of runs as needed to suit the 
openings. 

In roofs, combination storm panels are 
used with operated lines. With stationary 
lines short end panels are used. Either type 
of panel extends 2 feet beyond the sash,

usually to approximate line of truss center. 


Dimensions from out to out of these panels 
are always even feet: no odd feet, no inches. 
To these even-feet dimensions must be added 
not less than 11% inches at each end (more if 
desired) for clearance and end flashings. Thus 
opening lengths are expressed as, e. g., 84 ft., 
3 in.; 136 ft., 3 in.; etc. Clearances exceeding 


1% inches at each end must be filled out with 
additional flashing. 


The flexibility of Pond Continuous Sash allows it to adjust itself 
to unavoidable irregularities in structural work. 


The expansion joint is flexible in the plane of the sash. Members 
are shortened for clearness.

Sash heights are 3, 4, 5, and 6 feet, no inches. 
Clear heights of opening, from head girt to

fully maintained.

In ordering glass for replacement, the width 
and height of each light must be specified. 


P.O ND) (CO NENUOGS 


In ordering new sash, only the nominal 
length of the units need be specified. 


Pond Operating Device 
The operating device is an essential factor 
in the success of top-hung continuous sash. 
Since part of the weight of the sash must be 
lifted to open it, only a highly efficient device 


can open readily lines too feet and upward — 


in length. Such a device must be low in fric- 
tion, wholly free from torsional or other varia- 
tions under load which would produce unequal 
opening, and so designed and built as to do its 
work steadily, year after year, with no atten- 
tion beyond lubricating the operating power. 

Twelve years of successful use have shown 
these qualities to be embodied in preeminent 
degree in Pond Operating Device. Its ten- 
sion principle of transmission is equally ef- 
fective on short and long lines. Used in con- 
nection with spirals and counterweights to 
balance the sash load, it enables much longer 
lines to be operated than would otherwise be 
possible. Its low cost of maintenance becomes 
more notable as time adds to its record. 

For mass control of ventilation rapid open- 
ing is as important as long lines. Neglect 
to open the sash is sure to follow the installa- 
tion either of many short runs, separately 
operated, or a few long ones which are hard 
to operate. The value of Pond Operating 
Device lies in its ability to open long runs 
quickly.

is given on pages 93 to 96.

Structural Work Required 


This includes the following: 


Vertical supports (angles, channels or tees) 
for attaching brackets of operating device. 


For sash § or 6 feet high, the center to center 
spacing of supports should not be less 
than 7% ft. nor more than 16 ft.; for 
sash 3 or 4 feet high, the spacing should 
not be less than 6% ft. nor more than 14 
ft. (Trusses on 20 feet centers, with one 
intermediate, usually make the most 
economical arrangement for steelwork.) 


A continuous girt angle at the head, to 
which the sash hinges are bolted. This 
angle should not be smaller than 3 by 3 
inches, 14 to 3% in. thick. 


A continuous member at the sill. The face 
of this girt (usually an angle or a channel) 
should be in the same plane as the face 
of the girt angle at the head. 


A continuous girt angle between upper and 
lower lines of sash where both lines are 
to be operated. This member should 
be the same size as girt angle at head 
when sash above and below are both 
vertical or both sloping; but when sash 
above is vertical and sash below is slop- 
ing, the leg to which hinges for lower sash 
are bolted should be at least 4 in. long. 
(If the lower line is to be stationary, this 
angle may be omitted; but, unless it 
is used, the sash cannot later be changed 
to operated. If the angle is omitted, the 
uprights are to be punched for our clips

Top-Hung vs. Center-Pivoted 
Continuous Sash 
The attempt is sometimes made to avoid 
the obvious fault of pivoted ventilators for 
roof use (i. e., the fact that the gaps between 
them admit rain) by joining them into a con- 
tinuous line. We were the first to make center- 
pivoted continuous sash, having furnished 


70,000 square feet of it in 190g to the Pullman

the top edge of the sash when the sash is open. 
Snow and rain are easily blown over the top. 


But the greatest weakness of center-pivoted 
continuous sash is the virtual impossibility 
of making continuous contact at head and sill. 
Not only are the head and sill never in exact 
alignment save by accident (this happens 
also with top-hung sash, but does no harm 
if the errors are small), but the center line of 
support is probably not in line with either. 


With top-hung Pond Continuous Sash, a 
lateral wave in the sill girt is taken up by ad- 
justing the operating arms to pull the bottom 
rail into contact when the sash are closed. 
The flexibility of the sash permits this; and 
the top rail makes a tight contact owing to 
the hinge construction. 


But a center support turns each muntin 
into a lever. If the top of the sash strikes the 
head before the bottom makes contact, there 
is no cure, because bending the muntin would 
break the glass. If the bottom strikes first, 
the top remains open. 


Worst of all is the fact that an in-or-out 
misalignment of the center support is multi- 
plied by two in the sash itself. If the centre 
is one-half inch too far out, the top rail will 
meet the head when the bottom rail is still 
an inch from the sill. And faults in head 
and sill are likely to make the matter worse. 


With misalignment of head, center support 
and sill, the sash is likely to strike first at the 
bottom at one point of its length, and first at 
the top somewhere else, making a series of 
large air leaks for which no correction is 
possible. 


A. Top-hung Sash: no center pivot to interfere with contact 
at head and sill. 
Lower line drawings show effect of bad alignment of steelwork, 
when using center-hung continuous sash. 
B. Bottom of center-pivoted sash strikes sill too soon: top 
remains open. 
C. Bottom of center-pivoted sash does not meet sill when 
top is shut. 


D. Error in location of center pivot is multiplied by two at 
head or sill.

An old grey iron foundry 180 ft. wide, remodeled to secure more air and light. The roof originally had a low, wide 
monitor, one end of which is seen at the right, with a small monitor surmounting it. By building out the wide monitor 
and removing the small one, an approach to a Pond Truss form was obtained, with great increase in glass and venti- 
lating areas. 


It is intended later to put Pond Continuous Sash in short lengths between pilasters in the lower street wall, thereby gain- 
ing more light and inlet area to balance the outlets.

POND CONTINUOUS SASH, POWER HOUSE TYPE 


Pond Continuous Sash, Power House Type 
(Patented and Patents Pending by Clarke P. Pond) 


Pond Continuous Sash, Power House Type, 
is recommended for power houses and central 
stations of all sizes. The fact that it sheds 
water outside the building line permits the 
windows to be kept open during rains without 
risk of injury to equipment. The details at 
head, sill, jambs and mullions include double 
weathering contact all around when closed, 
thus minimizing air leakage. The heavy, rolled 
steel sections and oxy-acetylene welded joints 
of both the sash and framing insure permanent 
rigidity and minimum cost for maintenance. 


Architecturally the design of Pond Continu- 
ous Sash, Power House Type, is strikingly 
adapted to the rugged appearance which a 
power house requires. Its large lights, its 
heavy formed plate framing, and the imposts 
and mullions used in large openings, all con- 
tribute to the effect of massiveness. This 
effect is enhanced by the simultaneous control 
of all the sash in each opening, by which uni- 
formity of appearance is secured. 


In principle, and in the solid rolled steel 
members of which it is composed, Pond Con- 
tinuous Sash, Power House Type, is similar to 
Pond Continuous Sash as used in roofs and 
factory walls. For power houses, ‘however, 
the sash are arranged to hang vertically when 
closed; and the head, sill, jambs and mullions 
are arranged to make double weathering con- 
tacts. Upper and lower sash in an opening 
are connected by double arms and vertical 
bars, and these again are connected so that if 
desired, all the sash in an opening may be 
simultaneously controlled by Pond Operating 
Device, using a hand chain or electric motor 
according to the area of sash to be controlled. 


Standard sash heights, 3, 4, 5 and 6 feet, 
are used. All joints in sash are oxy-acetylene 
welded. Vertical muntins are 2 feet apart, 
and the width of opening is expressed in even 
feet plus the width of weathering and of jambs 
and mullions. See details on page 86. 


The structural work at head, jambs, sills 
and imposts is enclosed by formed plate steel 
of No. 12 gauge, which is assembled entirely 


’ 


by oxy-acetylene welding, except where it is 
necessary to make the frame in sections to 
facilitate transportation and handling. 
According to the width of opening, mullions 
may be used or omitted. If used, they may be 
of the external, formed plate type shown in 
detail at the foot of page 86, or internal struc- 
tural members as shown at the foot of page 87.

Page 87 shows a typical impost, with its struc- 
tural reinforcement. Upper ends of mullions 
enter the impost with slip joints to provide for 
. variations in measurement. The head rail sup- 
porting the sash next below an impost, like the 
intermediate rails, is of formed plate: it is at- 
tached only tothe mullions and jambs, not to the 
impost. If there are several imposts, each impost 
supports only the mullions resting on it. The 
upper mullions have slip joints in the head. 

In small spans, the sash are hung from two- 
piece formed rails without reinforcements. 


t 


External formed plate mullion. 


"View of sill from inside. 


For wide spans, rails with structural rein- 
forcements are used. Both rails are shown at 
the top of page 87. 

Internal mullions are I-beams or similar 
members, and are continuous from sill to lintel. 


Two forms of head are shown on page 86. 
One is used with imposts and external mul- 
lions: it has a slip joint as shown, to accom- 
modate variations in vertical measurement. 


Whatever form of mullion is used, heavy 
formed plate framing is used at jambs and sill, 
as shown on page 86. The double weathering 
contacts throughout will be noticed. 


We furnish and weld all the formed plate 
shown on pages 86-87. Bottom ends of plate 
mullions are welded to the sill or impost sup- 
porting them. Rails from which sash are hung 
are welded to jambs and mullions. 


Each weld covers the entire line of intersec- 
tion, making a complete union of the parts. 
No aud? is offered for water to enter crevices 
and cause internal corrosion. The same com- 
plete, integral welding is applied to all joints 
of the sash. 


One-quarter inch wire glass should be used. 
It may be smooth, hammered, or ribbed, as 
desired. Lights are bedded in“P.C.S.” putty 
and held at sides by glazing angles. The putty 
is struck off flush at top and bottom edges of 
lights, and drip holes in the outer flange of the 
bottom rail permit drainage when sash is open. 


Clearances required for Pond Operating 
Device are shown on page 88. Tension rods 


-and compound levers may be located to act on 


upper or lower sash, as preferred. When free, 
the sash hang partly open, hence the effort 
required to open or close them is minimized. 


Vertical supports are required for the com-

These views of the Highland Park power house illustrate the artistic possibilities of Pond Continuous Sash, Power House T ype. 
All the sash in each opening are connected by vertical arms and partially counterweighted by a heavy hoceonell bar as the interior 

view shows. Thus they tend to hang about 15 degrees open, and little effort is required to close them or open them further. 


By suitably designing the roof, even a large boiler house can be made light and comfortable in 
the firing aisles. The cross sectional drawings below show how this is done with a boiler house 
containing two rows of boilers facing on a common aisle. Air enters the firing aisle by one or 
both end walls, aided if necessary by occasional spaces between batteries of boilers. 


In a power house containing several aisles, the same arrangement can be repeated for each 
aisle. Ample inflow areas are necessary: they may be provided by steel rolling doors, one 
at the end of each firing aisle.

Pond Operating Device 


(Patented and Patents Pending by Clarke P. Pond) 


_The first test of a sash operator is the square feet of opening that it produces for a 
given effort in a given time. 


The second is its ability to repeat this performance indefinitely, with only nominal 
maintenance. 


To open a long run of top-hung sash on a slope is the severest duty required of an oper- 
ator, because part of the weight of the sash must be lifted to open it. Pond Operating 
Device is designed for this express purpose. Its long life in this difficult service results 
both from the care with which useless stresses and destructive friction are eliminated, and 
from the correctness of proportion and 
thoroughness in detail which ensure free- 
dom from breakdown in service. 


The tension principle oftransmission, used 
in Pond Operating Device, is fundamentally 
sound. Its non-rigid construction avoids 
trouble resulting from loss of alignment due 
to bending or other causes. It gives a 
flexible, nearly frictionless application of 
power, free from lateral stresses and involv- 
ing no difficulties in support and erection. 


Idler at end of hand-operated transmission line. 


The design is such that the thrust exerted 
by the sash rods increases rapidly, for a 
given pull on the chain, as the sash is 
opened. When closed, the bottom member 
of the sash is pulled up snugly against the oP ee cs 
sill. By using spirals and counterweights Pilrvourcr 
the length of line that may be operated gue oy long 
from a single power is doubled. are ae Spiral 
is 40 inches 
in diameter. 


Over large floor areas it is highly desir- 
able to have a slow, evenly-distributed air 
movement, which maintains ventilation yet 
is not felt locally as “‘drafts.”’ This is done 
by controlling both inlets and outlets in 
the longest possible lines, and having both 
sets of openings properly located and 
balanced as to area. Pond Continuous 
Sash should be used in roofs: in side walls 
the same sash may be used either altogether 
or in one or two lines over the sliding 
windows; or a connected line of pivoted 
ventilators above the lower sash may be 
operated by Pond Operating Device. 


Housing of hand-operated power. 
The view on the opposite page 
shows the cut steel worm, ball 
bearings, integral sprocket and cut 
steel worm wheel, shaft, and the 
dust-proof cover which encloses 
the worm gearing. The hand-chain 
wheel and guard are also shown. 


For such applications of Pond Continu- 
ous Sash, motor-driven Pond Operating 
Device permits the use of continuous runs 
up to 1000 feet long if desired, or of paired 
upper and lower runs up to 500 feet long.

POND “OPERATING DEVICE 


Mechanism 


The transmitting mechanism consists of two 
tension rods, connected at the operating end by 
a sprocket chain and at the other end by a link 
chain passing over an idler pulley. To these 
rods, moving in opposite directions, are attached 
compound levers having their fulcrums at sta- 
tionary brackets and their other ends connected 
to the sash rods. These exert an angular thrust 
which becomes increasingly direct as the sash 
is opened. Since they work alternately right 
and left, the angular components neutralize 


Parts of hand-operated power. See names on opposite page. 


oh) 


each other. As the sash rods act on the levers, 
not the transmission rods, they exert no “back 
thrust” against the latter. 


As the transmission rods are subject only 
to tension, they are very light and flexible. 
Instead of working in guides, they are sup- 
ported by the compound levers, on which they 
float with negligible friction. 


The operating power contains a cut steel 
worm and gear, enclosed in a dust-proof, 
grease-packed case. The worm holds the sash 
at any angle, thus preventing slamming and 
breakage of glass. Friction is minimized where- 
ever possible: the worm shaft runs in ball bear- 
ings, and all plain bearings in the transmission 
line are phosphor bronze. 


The rods are steel, in 20-foot lengths, with 
ends hot-headed and connected by pressed 
steel couplings. Two stops are attached to the 
sprocket chain, by which undue strain on the 
transmission and sash is prevented. 


Bearings in the idler pulley and compound 
levers are phosphor bronze. Lubrication is 
required only in the gear case, which should 
be repacked with grease once a year. 


Width of Opening 
In a heat-producing building especially, the 


practical value of the sash for ventilation 
depends on the ability to open it easily and 
quickly. If in a foundry, for example, it is 
necessary after a shower or after pouring a 
heat for many men to stop and operate hand 
chains, ventilation is certain to be neglected. 
The men will endure discomfort rather than 
exert themselves. 


Pond Operating Device gives a wide opening 
quickly, and absorbs little power in friction 
when operating long lines. Following are 
guaranteed openings of Pond Continuous Sash 
with Pond Operating Device.

Spirals and Counterweights 
The idler pulley described on page gs is suited 


to hand-operated runs of from 150 to 300 feet 
in vertical openings, depending on the height 
of the sash (150 feet for 6-ft. sash, 300 for 3-ft. 
sash). On the standard slope of 30 degrees, such 
runs may be from Ioo to 200 feet long. 


By using spirals and counterweights the 
above lengths of run are doubled, thus reduc- 
ing by one-half the number of operating powers 
required for long runs. In a large plant this 
is especially desirable, on account of the time 
saved in opening or closing the sash. 


The spiral is used in place of the idler pulley, 
and the counterweight is hung on a steel cable 
which winds on the spiral. Thus a tension is 
applied to the transmission rods which balances 
the weight of the sash: hence the operator has 
only to overcome friction. 


As the sash rises the weight descends, and 
the larger radius of the spiral comes into play; 
hence the leverage is greatest when the load 
is greatest. A guide and automatic safety 


device are included with the device. 


Spirals and counterweights must be specified 
in bid and order if desired. They should be 
used in all cases where additional powers, with 
the consequent time needed to operate them, 
can thereby be saved. They are an exclusive 
feature of Pond Operating Device. 


Spirals and counterweights are very desir- 
able for motor-operated runs. They make the 
motor load and speed substantially uniform, 
and prevent excessive overload on starting the 
motor with the sash already partly open. For 
very long motor-operated runs they should 
always be used. See page gg.

POND OPERATING DEVICE 


Pond Operating Device, Motor Driven 


In a small shop, one man, by opening a few 
ventilators and operating a few chains, may, 
if necessary, control the entire ventilation. 


But, the larger the building, the more likely 
is control to be left to the impulse of workers 
nearest the ventilators and operating chains. 
The more likely, therefore, are the outlets 
to be left shut, and the inlets to be opened 
haphazard. 

Under such conditions bad air is probable 
somewhere, no matter how well the building 
be planned. And that probability is increased 
by the greater width of floor to be reached 
by fresh air. 

Pond Operating Device, Motor Driven, 
enables the great industrial plant to be ven- 
tilated with the same precision and complete- 


ness as the small shop, by co-ordinated, uniform 
control. And the process is even easier. 


Obviously the ventilating needs of a factory 
or foundry are the same if the interior pro- 
cesses are the same, no matter how far the 
floor may extend. Whatever outlets and inlets 
are appropriate to the wind and season at 
one end, are appropriate also at the other. 


By making these outlets and inlets uniform 
and continuous throughout the length of the 
building, and of width suited to the season 
and the wind, a slow, uniform air movement 
results, covering every part of the floor but 


devoid of “drafts.” 

This result is accomplished by operating all 
sash by motors, with switches so located that 
both inlets and outlets may be regulated by

foundry. The two lower lines of sash are connected by vertical arms, operated by one motor, and balanced by a spiral

the same person, preferably the foreman or shop 
superintendent. To control the air change for 
any condition of wind or weather, or for any 
change of heat in manufacture (as when pour- 
ing in a foundry), then becomes merely a 
matter of pressing buttons. 


Thus it is possible to combine the efficient 
organization of the great industrial plant with 
even more than small-shop facility in ven- 
tilation control. If the building itself be prop- 
erly designed, the air in it need never become 
stale or overheated. 


If certain bays require separate control, their 
switchboards can be located accordingly. 
Sometimes the floor space is divided between 
different departments having markedly dif- 
ferent ventilating requirements; as, for exam- 
ple, the molding floor, the cleaning floor and 
the core department of a foundry. If these 
are under one roof, each should have its own 
sash control. 


Among buildings without heat-producing 
processes the factory of the Dayton-Wright 
Airplane Company, Moraine (near Dayton), 
Ohio, is a striking example of the value of motor- 
controlled ventilation. This building, 280 ft. 
wide and 1000 ft. long, contains many depart- 
ments of airplane manufacture, with few parti- 
tions between them. If local sash control 
were used the building would be badly ventil- 
ated most of the time. Instead, the sash are 
grouped in runs of from 400 to 600 ft. each, 
with the motor control stations so located, 
that it is a simple matter to open or close the 
sash to suit the weather and wind for the entire 
building. There are no local drafts, and the 
air is always fresh. 


According to the work and other conditions 
in the building, it may be best to locate the 
simultaneously controlled side wall openings 
close to the floor, or above the windows, or to 
fill the entire wall with them. An example of 
the last kind is the Bunting Brass & Bronze 


Company foundry (see insert) where the 
heat from 32 large furnaces demands excep- 
tionally rapid air renewal. Here the side walls 
are filled with Pond Continuous Sash having 
upper and lower runs connected in pairs and 
operated by electric motors, with spirals and 
counterweights to equalize the load. 


The best results in large one-story buildings 
are gained from the use of a Pond Truss roof, 
with Pond A-frames for inlet between Pond 


Trusses where two or more must be used.

runs in power house roofs, and to other loca- 
tions where the height above the floor would 
make hand chains undesirable.

applications one of two purposes obtains:

take too long and probably be neglected. 


2. To operate many sash quickly, as in a 
large foundry in winter, when it is desired to

POND TRUSS ROOF DESIGN 


(Patented by Clarke P. Pond) 


The Pond Truss roof was originally designed for foundries and similar buildings where 
heat and gases are produced. It differs from all other roofs in the rapidity and thorough- 
ness with which it clears the building of heat, smoke and foul air. Its outlets are large, 
and are placed to the best advantage for receiving ascending heat currents with minimum 
lateral drift. Currents striking the steep planes of the V-shaped portion are swept directly 
to the outlets. There is no place anywhere where stale air can be pocketed. 


The remarkable efficiency of the Pond Truss, both in ventilation and in light distribu- 
tion, has led to its adoption for manufacturing buildings in many kinds of industries. These 
include rubber works, machine shops of all kinds, glass works, airplane factories, and others, 
both single and multiple-story buildings. Where skilled workers are closely crowded, or 
where fumes or odors require extra ventilation, the Pond Truss is especially valuable. 


As applied to heat-producing buildings, owing to the light from behind them.

This foundry is unusual in design because, owing to the nature of adjacent property, it was impracticable 
to use openings in the lower walls. Consequently maximum use had to be made of the upper walls by 
placing two operated lines of Pond Continuous Sash in each. In addition, the end walls are almost entirely 
filled with Pond Continuous Sash. 

The building is interesting also because it was erected by stages as required by the growth of the business.

original foundry was 400 ft. long, and the business grew so rapidly that within two years another 600 ft. 
had to be added, the original design being extended. Pond Continuous Sash, hand operated by Pond 
Operating Device, is used throughout, except in the street front, where Lupton Pivoted Sash is used.

ment, material storage, core department, cleaning and shipping departments, and lunch and locker rooms, 
are housed each in a specially-designed building, with all departments closely grouped and related. The main 
foundry building, 490 feet long, has a Pond Truss roof, with Pond Continuous Sash controlled in long runs 
by Pond Operating Device, motor driven. Lupton Pivoted Sash is used in the walls, the upper ventilators 
. being controlled by Pond Operating Device with hand chains. 
The entire plant, with the exception of the offices, is equipped with Lupton Pivoted Sash and Pond Con- 
tinuous Sash. Free use is made of Pond A-frames in the auxiliary buildings, also of Pond Operating Device 
for simultaneous control of the pivoted ventilators in the upper side walls.

LUPTON, COUNTER BALAN CE Dies Ace 


Lupton Counterbalanced Sash 
(Patented) 


The characteristic feature of this sash is its balanced top and bottom ventilation. 


Under many conditions this equality of upper and lower openings is a feature of the 


greatest value. 


It is obtained by hanging both upper and lower sash of a pair over a 


single set of pulleys, so that both open or close simultaneously. 


This arrangement reduces by one-half the motions needed to open or close a line of windows. 
But—more important than that—it makes it certain that the upper sash will be opened. 


Fresh air cannot enter unless an equal volume goes out; and the usual exit is by the upper 
sash. Few workers in factories, however, if left to themselves, trouble to open the 


upper sash. Those near the windows get 
enough air anyway, and those further back 
do not think of it. Hence, unless a wind is 
blowing through, the air becomes stagnant. 


And what is true of factory workers 1s too 
often true of other persons. No one likes to 
bother with the upper sash. The first and 
greatest value of Lupton Counterbalanced 
Sash is that it makes balanced ventilation 
“automatic.” 


Lupton Counterbalanced Sash has also 
certain mechanical features of value. It does 
not encroach on floor space when open, or 
interfere with the use of shades or screens. 
It is rugged in build, very durable, and 
very resistant to air leakage and weather. 
It is free from any tendency to warp and 
stick. The counterbalanced feature permits 
very simple construction. 


The best appearance results from using 
two vertical muntins. Horizontal muntins 
are not recommended. Sash look better 
without them, and cleaning is simplified. 
In actual practice there is less breakage 
with large lights, because breakage is due 
chiefly to carelessness, and men are more 
careful when working near large lights. 


The fact that the same type of sash may 
be used for all exposures permits a uniform 
window treatment, regardless of fire haz- 
ards. See ‘Underwriters’ Labels,” below. 


Lupton Counterbalanced Sash is best 
applied in these types of buildings: 


1—In wide multi-story buildings, for the 
ventilation given per square foot of sash; 


2—In single story buildings where heat 
or gases demand unusual inflow areas; 


Lupton Counterbalanced Sash in office portion of factory 
building. Note the narrow mullions and large glass area. 


Lupton Counterbalanced Sash with stationary glass panels 
underneath to increase the light. See upper building opposite. 


LUPTON COUNTERBALANCED. SASH 


3—In any building where its strength, easy cleaning (due to large lights) and fine appear- 
ance, together with its balanced ventilation, make it preferable to ordinary types of 
sash. Because of these qualities it is often used for office buildings, schools, commercial 
buildings and the like. 


Sometimes combinations of Lupton Counterbalanced Sash and Pond Continuous Sash 
are useful. ‘Thus, in a multi-story building, a series of uniform openings above the slid- 
ing sash permits a slow air movement to take place over the entire floor, instead of 
the usual local drafts and stagnant areas. If, however, the ventilating demands are very 
exacting, as where heat or fumes are produced, it is better to have a continuous inlet, as 
well as outlet, by substituting Pond Continuous Sash in upper and lower lines. 


Standard Sizes 


Lupton Counterbalanced Sash glass sizes are 
14, 16, 18, 20, 22 and 24 inches wide, and 36, 24, 
48, 54, 60, 66 and 72 inches high. Any desired 
combination of width and height may be had, 
though two vertical muntins are advised. For 
Underwriters’ windows see under “Under- 
writers’ Labels.” 


For industrial buildings we recommend 
sash units between ¢ feet and 6 feet wide. A 
line of these wide windows is opened with 
fewer motions, and makes a better appearance. 
It is also cheaper to install and maintain. 


Where Lupton Counterbalanced Sash and 
Pond Continuous Sash are used in the same 
openings, it is best to use special glass widths 
Lupton Counterbalanced Sash in factory, 88 ft. wide with for the Pond Continuous Sash. See typical 


12 ft. ceilings. Stationary glass panels under sash increase elevation and details, page 122.

LUPTON” COUNTER BALAN GED 


SASH 


Either single or multiple unit openings 
may be used. If multiple, their width is 
obtained simply by adding the widths of the 
several units, as these are figured to the center 
lines of jambs and mullions. 


Sash Members 


The members are heavy one-piece rolled 
sections, which are not subject to the internal 
corrosion that occurs with built-up sections. 
Corners are oxy-acetylene welded, and the 
ends of muntins are riveted. Meeting rails 
interlock, and require no weather stripping. 


Frame 


All frame members are rolled steel, and 
present little exposed surface requiring 
painting. The sash members make double 
contact with them to reduce air leakage. 
The jambs and mullions have a central pro- 
jection, on which the parting strips are tightly 
seated, and bearing shoulders for the sash rails, 
so that when zinc weathering is used the sash 
cannot cut the weathering. 


The sill is especially noteworthy. With 
only ordinary care in painting, it averts 
altogether the rust-staining of the masonry 
sills which is so common and unpleasant with 
metal windows in otherwise sightly build- 
ings. This is done, first, by eliminating all 
needless exposed area; second, by leaving 
no horizontal surface exposed when the 
window is shut; third, by making the sill of 
copper bearing steel, whose high resistance 
to corrosion is well known. 


Paint deteriorates fastest on a_ horizontal 
exposed surface. In Lupton Counterbalanced 
Sash this surface is so narrow and _ so well 
sheltered that deterioration is minimized. 


Parting strips are rolled H sections, flared 
for line contact with the sash to minimize 
friction. Their alignment with the jambs 
and mullions is fixed by shoulders integral 
with the latter. For industrial buildings 
this is sufficient without weather strips; but 
for offices and schools zinc weathering strips 
forming double contact should be added. Zinc 
weathering is furnished only where so speci- 


fied in bid and order. 


Substantial roller-bearing pulleys are used. 
After the sash are erected the space above 
the head is grouted and finished smooth. 


Hardware 


The hardware is in keeping with the superior 
construction of the sash. Malleable lift 
handles are regularly furnished; also malleable 
cam locks for basement and first floor. Locks 
are furnished above the first floor only when 
specified in bid and order.

Lupton Counterbalanced Sash is used on account of its heavy members, oxy-acetylene welded joints, and consequently 
greater durability than is afforded by the pivoted-ventilator type of sash. Ventilation, though effectively given, is of 

secondary importance.

Lupton Counterweighted Sash. 


(Patented) 


Lupton Counterweighted Sash is intended for hotels, office buildings, libraries, and 
other high class structures, in which substantial construction of the sash, fire resistance, 
weatherproofness, and maximum opening for air and light are desired. Its construction 
is exceptionally fine, the details are thoroughly adequate, and every feature is in keeping 
with the exacting character of the intended use. 


The upper and lower units of the sash are separately hung with counterweights, hence 
either can be opened independently. 


Lupton Counterweighted Sash has an unusually high ratio of glass to opening area. 
This is due to the thin lines of its solid rolled 


steel members, and to the concealment of 
almost the entire jamb in the masonry. 


Aside from its value for effective lighting 
and ventilation, the small exposure of 
painted steelwork is important. Even the 
sill, where paint deteriorates most rapidly, 
has almost negligible exposure to weather. 


Sash Details 


The sash members are heavy one-piece 
rolled steel sections, oxy-acetylene welded at 
the corners and having riveted muntins. 
Two vertical muntins make the best appear- 


ance, but one or three may be used if size of 
sash warrants. Horizontal muntins are best 
omitted, as large lights make a more dignified 
appearance and simplify both cleaning and 
painting. If they must be used—as in Under- 
writers’ windows—their narrow lines are much 
more agreeable to the eye than wide muntins 
would be. 

The sash rails make a double contact at 
head, sill, jambs and mullions. The one- 
piece meeting rails interlock tightly without 
weather strips. 


Roller bearing pulleys of ample size are 
used. 


Frame Construction 
The jamb members are solid rolled steel 
sections of special shape, having a central 
projection by which the parting strips are 
accurately aligned. These strips are of H The narrow lines and large lights of Lupton Counter- 
section, flared to make a line contact with weighted Sash admit abundant light.

steel plate: they are fitted over cast iron 
bases rigidly bolted to the sill. A removable 


section in each jamb member permits the

For the high-class buildings in which Lupton 
Counterweighted Sash is used, the sill con- 
struction is of especial value. It avoids alto- 
gether—with only ordinary care in painting— 
the familiar rust stains that so often deface 
the sills of otherwise attractive buildings. 
This result is due, first, to elimination of all 
needless exposed area; second, to no horizontal 
surface being exposed when the window is 
shut; third, to the use of copper bearing steel. 

A horizontal painted surface, exposed to 
weather and to splash from concrete and mor- 
than 
By reducing the horizontal surface 


tar, deteriorates much _ faster vertical 
surfaces. 
of the sills as much as possible, and protecting 
it when the lower sash is closed, the frequency 
of painting is minimized. 

Mullions are formed by placing adjoining 
weight boxes together. A very effective treat- 
ment is to face them with cut stone or terra 
cotta. The interior is finished with a formed 
steel strip, which covers the space between the 
weight boxes. Through expansion bolts hold 
both the masonry facing and the steel plate 
in position. If preferred, a steel plate may 
be used for exterior finish. 


Standard Sizes 
Standard glass sizes are 14 to 24 inches 
wide by even inches, and 36 to 72 inches high 
by multiples of 6 inches. See reference to 


muntins, under “Sash Details.”

PouProNne PROJECTED SASH 


Lupton Projected Sash 


Lupton Projected Sash is adapted to schools, hospitals, institutional and office buildings, 
and other conditions requiring a thoroughly serviceable window at lower cost than the 
sliding types. It is especially useful for schools and hospitals, and for office portions of 
industrial buildings using Lupton Pivoted Sash elsewhere. 


Lupton Projected Sash was first made in 1911, and was the first window of its type to 
be made of steel. It has hitherto been used chiefly in hospitals, but has recently been 
put on a production basis, thereby greatly reducing the manufacturing cost and making 
it available for many other classes of buildings as well. We believe it to be the most 


E37 


satisfactory all-around window for schools. 


The characteristic and exclusive feature 
of Lupton Projected Sash is the balanced 
ventilator with adjustable friction shoes to 
hold ventilator open at any angle, with- 
out the use of stay bars or similar fasten- 
ing devices. Without these friction shoes, 
even a well balanced ventilator will blow 
shut in the slightest wind. Each ventilator 
is guided at one edge—top or bottom—and 
opens at the other. 


As usually designed, each window is 
divided horizontally into three equal sec- 
tions, of which the middle one is stationary. 
For hospitals, however, the entire window 
is filled with inwardly opening ventilators, 
giving an out-door effect without drafts. 


Two Types of Ventilators 


The ventilators are of two types. One 
swings outward at the bottom and is guided at 
the top. The other swings inward at the top 
and is guided at the bottom. In either case, 
the ventilator is projected entirely inside or 
outside the vertical plane of the sash. If 
desired, outward-swinging ventilators at top 
and inward-swinging ventilators at bottom 
may be specified for the same window. Both 
types are alike in price. 


This complete freedom of choice, in use 
of either type of ventilator or both, permits 
the architect to plan solely for the best result. 
For example, in southern schools, where maxi- 
mum fresh air is the objective, both top and 


LUPTON PROJECTED SASH 


bottom ventilators will usually be arranged 
to open outward, thereby acting as shelters 
over the openings. If desired, the entire glass 
area may be given to ventilators. 

In more northern latitudes the top ventilator 
will still open outward, but for the bottom ven- 
tilator the inward movement is sometimes pre- 
ferred, as that makes the ventilator in effect 
a windshield, deflecting air currents upward. 

In hospitals and when outside screens are 
to be used, all ventilators should open inward. 


Details 

Details of construction are shown in the 
illustrations. The ventilators make a double 
contact all around when closed, and are care- 
fully fitted to minimize air leakage. The 
bronze friction blocks slide in the stationary 
frame members, and are backed by compres- 
sion springs and adjusting screws. Thus each 
ventilator can be separately adjusted accord- 
ing to its size and weight, so that it will hold 
securely when open, yet without unnecessary 
friction. This may be done not only by the 
erector, but by the user at any time, using an 
ordinary screw-driver. | 

Each ventilator may be swung over, so 
that both sides of the glass may be cleaned 
from the inside of the building. 

All ventilators have corners solidly oxy- 
acetylene welded, thus securing freedom from 
internal corrosion, plus the rigidity of a one 
piece framework. ; 

Ventilators opening out at the bottom may 
be equipped with a special cam latch or a spring 
catch and chain. 


Standard and Special Sizes 

Standard sizes are shown in diagram on 
page 140. The method of operating ventilators 
is optional, with no difference in price. 

At a higher price we will furnish Lupton 
Projected Sash in special sizes, or entirely 
filled with ventilators opening in or out as 
specified. It is well to consult us, stating the 
use intended. 


Where Lupton Pivoted Sash is used in an 
industrial building, it is very desirable to use 
Lupton Projected Sash in the office portion. 
For that purpose we will furnish Lupton Pro- 
jected Sash to match the Pivoted Sash, with 
similar muntins and glass lights and with ven-

This _pro- 


duces complete architectural harmony between 
the two types of sash, with appropriate use 
of each.

Ventilator dimensions should not exceed 
sixty inches in width or thirty-five inches in 
height when ventilators are one light high, or 
fifty inches in width and forty-one inches in 
height when ventilators are two lights high. 
By keeping within these limits undue torsional 
stresses on the glass and putty are avoided. 


Lupton Underwriters’ Projected Sash 


When so specified we will furnish Lupton 


139 


Projected Sash with Underwriters’ Labels. 
Such sash are limited to 350 square inches of 
exposed glass per light, and must have % by 
34 inch glazing angles. Labeled windows must 
not exceed dimensions of 7 by 12 feet per 
window unit; but by using standard T-bar 
mullions several units may be used in one wall 
opening. 
they must be specified in the order and included 
in the estimate. 


If labeled windows are desired, 


Computing Sash Sizes from 
Glass Sizes 


Sizes of Lupton Projected Sash are figured 
from glass sizes, or glass sizes from sash sizes, 
by the same formulas as for Lupton Pivoted 
Sash, as follows: 


For width or height of single sash 
units: Add 36” to width (or height) of 
each light, multiply by number of 
lights wide (or high), and add 7". 


For width of multiple sash units: Add 
together the widths as above of the 
various units in an opening, and add 
2" for each standard T-bar mullion. 


Glass sizes are figured as for stationary 
lights. Lights in ventilators are reduced 
1 inch on each edge adjoining an outer edge 
(top, bottom or sides) of the ventilator. 


The above formulas refer to nominal sash 
sizes, which are taken to an imaginary line 54 
inch inside the outer edges of frame members 
all around. This > inch on each edge repre- 
sents bearing surface in jamb, head or sill. 
Hence nominal sash sizes and wall opening 
sizes are identical. 


Painting, Erection and Glazing 


All Lupton Projected Sash are given a 
thorough shop coat of paint before shipment. 
They should receive at least two field coats 
after erection.

SASH 


Erection and glazing follow the same rules 
as for Lupton Pivoted Sash. Brick and con- 
crete walls require grooves in the jambs, and 
concrete lintels require a similar groove. Brick 
openings taking only one sash unit per open- 
ing must be made with a reveal in the jambs, 
or one jamb must be left unfinished until 
sash are inserted. 


Steel Windows for Schools 

It is illogical but true, that buildings repre- 
senting otherwise the last word in safe and 
durable construction should even today be 
equipped in most cases with wood windows. 
The reason for it is that, while steel windows 
‘have for years been successfully used in offices 
and industrial buildings, types designed for 
schools are of very recent origin. The high 
price of office steel windows has limited their 
use in schools. On the other hand, factory 
types of steel sash do not lend themselves well 


to architectural treatment or to the use of 
shades and screens; and they cannot readily 
be adjusted to small degrees of opening, such 
as classrooms require in winter. 


All these objections are overcome by Lupton 
Projected Sash and—where sliding windows 
are desired—by Lupton Counterbalanced Sash 
with zinc weathering. By using either, a more 
durable window is secured, impervious to 
moisture; permanently free from warping, 
looseness and rattle, and free from the necessity 
of periodic weather stripping to keep it tight. 
In case of fire, steel windows retard or prevent 
the spread of flames from floor to floor. Hav- 
ing narrower surfaces, steel windows admit 
more light than wood and require less paint. 
Finally, the first cost of Lupton Projected Sash 
is little if any higher than that of high-class 
wood windows, while the return in service, 
moderate upkeep, and durability is far greater.

APARTMENT AND RESIDENCE 
WINDOWS 


Lupton Projected Sash, Opening at Side 


To achieve the slender and beautiful lines of the English steel casement in residences 
of moderate cost, has for years been the dream of American architects. But the cost of 
such casements, of standard hinged construction, places them out of reach of the majority 
of homes. Hence the architect, even of fine brick, stone and stucco houses, is obliged to 
use conspicuous frames and trim of an inferior material. And, to avoid the obtrusive 
effect that would otherwise result, he must subordinate the masonry treatment of the 
openings, and place added emphasis on other features—porches, gables, etc.: with the net 
result that the windows control the architectural scheme instead of being subordinate to it. 


In Lupton Projected Sash, opening at side, we have combined the architectural qualities 
of the steel casement with good mechanical design and moderate cost. With that problem 
solved, it becomes possible to give a new beauty and dignity to residences composing the 
great bulk of American homes. | 


But, strong as is the charm of these small casement-like windows for the architect, 
their appeal to the mistress of the home is 
even stronger. They cannot swell, warp, 
shrink or loosen. They never keep people 
awake at night by rattling; and they draw 
evenly and snugly shut when closed. They 
never need weather-stripping: the original 
fit is permanent. 


With Lupton Projected Sash, an opening 
in the wall really means light and air: it is 
not cluttered with the meaningless lines and 


surfaces inseparable from wood sash. It is 


not even limited to half the opening area 


for ventilation, for the entire opening may 
be made a part of out-doors. Hence an 
opening may be smaller, if desired, for 
equal net result; and this makes a saving 
in heating cost. 


Mechanically these windows are identical 


with Lupton Projected Sash for schools, offices 


and hospitals. The radius arms are located 


at top and bottom: the sash open at the side— Projected Sash, opening out at side, with stationary transom.

has the usual bronze friction shoes, with 
adjustable spring pressure. The appearance 
when open very closely resembles that of the 
hinged casement, as the illustrations show. 


For the class of residences intended, the 
Lupton projected movement has a distinct 
advantage. The sash is steadied at both top 
and bottom: it requires no adjuster or fastener 
to hold it open: and it readily permits an 
opening-out sash to be washed from the inside. 


Still another point in its favor is the fact 
that the movement of the sash takes place 
wholly on one side of the plane of the window, 
leaving the other side free for shades or screens. 
If the sash opens in, permanent or semi-per- 
manent screens may be used, and separate 
shades or curtains attached to the sash. If 
the sash opens out, any form of shades may be 
used, with movable interior screens. 


Projected Sash, opening in at side, with stationary transoms. 
Permanent outside screens may be used with this type, and 
shades attached to sash. Several units may .be placed side 
by side in an opening. 


Stationary transoms form a part of all these 
windows, as the illustrations show. They con- 
tinue the lines of the muntins and allow awn- 
ings to be used with opening-out sash. 


Lupton Projected Sash, opening at side, 
are made of the same bars, and are erected in 
the same manner, as Lupton Projected Sash 
for schools. A double weathering contact is 
made on all sides, and the corners of the sash 
are solidly oxy-acetylene welded for rigidity. 
A plain malleable iron cam lock is the only 
hardware. Lights of sizes specified by the 
architect are used. We recommend that glaz- 
ing be done from the outside: Lupton Case- 
ment putty should be used, as litharge putty 


will crack away. 


Interior wood trim of any sort may be used; 
or trim may be omitted and a pleasing effect 
secured by finishing the plaster and wall paper 
against the window frames. When wood trim 
is omitted it is best to attach shade and curtain 
brackets to the steel sash, or to place wood 
fixture blocks in the plaster jambs at the head 
of the window to receive these brackets. 


For residences and apartment houses, we 
recommend that the moving portions of out- 
ward-opening projected sash do not exceed 30 
inches in width and 48 inches in height. In- 
ward-opening sash should be narrower, pre- 
ferably not exceeding 20 inches, in order not 
to obstruct the space near the windows when 
open. For large openings it is better to use 
multiple sash, with mullions to separate the 
units, than to use a correspondingly wide unit 
with ventilators exceeding the size limits 
mentioned. 


Lupton Projected Sash, Opening

Where bedroom or bathroom windows face 
the windows of an adjacent house, it is desir-

plished by the use of Lupton Projected Sash, 
opening in at top. 

The standard Lupton projected movement 
is used, and. the same steel members, but 
preferably arranged for glazing from outside. 
With the upper sash glazed with translucent 
glass, and the lower sash curtained, privacy 
is assured even when the sash are opened to 
a considerable width, as the illustration shows. 


Projected Sash, opening in at top. For all windows facing 
windows in adjacent buildings. Curtains and shades are 
attached to sash. Note how sash reverse for cleaning the 
outside. The friction movement holds them at any opening. 


Like all Lupton Projected Sash, these sash 
make a double weathering contact all around, 
and close with a snug, true fit that eliminates 
all need of weather stripping. The narrow 
lines of the steel afford maximum passage for 
light and air. The sash can be reversed to the 
position shown for washing the outside of the 
glass from inside. 

The sash are balanced against gravity for 
any desired opening, and the friction shoes 
hold them steady. They do not shake or 
rattle in the wind. 


148 


Shades are attached to the bottom of each 
sash, and draw upward as illustrated. One- 
piece screens are used outside. 


Lupton Projected Sash, installed, cost less 
than good wood windows. In weather tight- 
ness, durability and low cost of maintenance 
the advantage is wholly in their favor. 


Lupton Security Window 
The Lupton Security Window fills a definite 


need for a strong steel window, for basement 
or garage, which can be locked securely either 
shut or slightly open for ventilation. It is 
hinged at the top, and may be secured by a 
padlock either shut or held open by a 5-inch 
steel stay bar. 


Owing to the small size of the lights—7 x 10 
inches—entrance cannot be effected by breaking 
the glass; hence it is unnecessary to use a pro- 
tective grill outside. As the window may be 
hooked fully open, it fulfills every function of 


Lupton Security Window. Locks securely when closed, and 
when open 5 inches. The small lights of glass prevent in- 
truders from entering by breaking glass.

a cellar window, including that of receiving 
coal. 

Standard windows are 4, 5 and 6 lights wide 
and 2, 3, and 4 lights high. They are hinged 
at the top and open in. Standard hardware 
includes catch and 5-inch bar, but not the 
padlock. The cost is less than that of wood 
windows plus grills. Erection is simply a 
matter of setting the flanged frame of the sash 
into the masonry when the wall is built. 


Lupton Basement Windows 


These are of two types: 

(1) Standard Basement Windows, hinged 
at top and opening in, and having lights of 
standard sizes. 

(2) Projected Basement Windows, having 
the regular Lupton projected movement,

size lights as ordered.

Their cost of installation is very small, as they 
require no wood frames, but are set directly 
into the masonry when the wall is built.

LUPTON DOUBLE HUNG WINDOW 


(Patents Pending) 


The Lupton Double Hung Window is a notable achievement in this kind of window 
construction. It is unique in detail and obviates the common faults of ordinary win- 
dows of this type. The sash have no sidewise movement. They are easily opened and 
closed, and the window is of permanent construction, weathertight and fire resisting. 
Because of these qualities and also because of the excellent appearance of the window it 
is particularly suitable for use in office buildings, hotels, libraries, telephone exchanges, 
banks, educational buildings, dormitories and other buildings of the higher grade. 


The jambs, heads and sills project but little (d) One piece head and sill welded solid to

head and upper rail of sash. 

(f) Double contact between lower sash rail 
and sill designed to permit free drainage of

Lupton Double Hung Windows are made 
from heavy gauge steel plate. The windows 
may also be made of bronze, using plates of the 
same gauges that we have standardized for steel. 


Many features of the window are exclusive; 
the more important being— 


(a) Lateral adjustment of the sash obtained 
by the use of sash guides which interlock and 
form a close contact with sash rails. This 
arrangement practically eliminates air leakage 
and minimizes friction. 


i Standard hardware is polished bronze and

desired and at a corresponding difference in 
price. Standard bronze hardware will always 
be furnished unless otherwise noted in bid or 
order. 

When desired this window may be made to 
conform to the requirements of the Under- 
writers’ Laboratories and bear their label. In 
all such cases it is necessary to furnish muntins 


as the exposed area of each light must not 
exceed 350 square inches. One quarter inch 
wire glass must be used. These additional 
features increase the cost and if they are re-

LUPTON CASEMENTS 


Casements are the highest form of window construction, because of their fine workman- 


ship, strength, rigidity, permanence and finish. 


Lupton Casements have all of these features in their highest degree and are intended 
for use in buildings where accepted architectural principles of design are of prime impor- 
tance. Monumental buildings, educational buildings, public libraries, banks, fine residences, 
hotels, first class office buildings and other buildings of the same general character, are 


included in the class to which we refer. 


Construction 


The bars used in Lupton Casements are 
shown in full size on page 152. They are made 
from low carbon steel, produced from our own 
rolls and process straightened. They are de- 
signed to make a double contact at all points 
of closing and their unusual weight provides 
strength, rigidity and permanence. 


All corners are accurately machined and 
welded solid. The excess metal deposited dur- 
ing the process of welding is carefully ground 
off, leaving perfectly smooth and finished joint- 
less surfaces. Continuous metal drips at heads 
and sills are applied where necessary. These 
may be either steel or bronze, but your speci- 
fications should clearly state which metal you 
desire. 


It is general practice to furnish glazing beads 
on casements but they may be omitted if so 
desired. Our standard glazing bead is Section 
No. 351. This is applied to all four sides of each 
glass opening. In cases where condensation 
is a factor, Section No. 354 is substituted as the 
glazing bead for the lower edge of each light. 
It is made from extruded bronze and has a 
concave upper surface to collect condensation. 
It mitres with Section No. 351, which is used at 
the sides and top of each light. 


Usual building construction permits the 
casement frame to be set directly into grooves 
or reveals in the masonry, but it is sometimes 
desirable to have an auxiliary frame to givea 
broader appearance to the frame or to accommo- 
date some unusual detail of construction of the 
window openings. These frames are formed 
from heavy gauge steel plate.

small casements is not general. When small 
panes are desired it is customary to use leaded

to the use of steel muntins. 


Hardware 

The finish hardware may be furnished either 
in solid bronze or malleable iron. It is of our own 
design and made for use on Lupton Casements. 
The photographs in this 


shown section 


LUPTON, CASE MEN Ts 


give a general idea of the character, appearance 
and application of various pieces. These, how- 
ever, show only the hardware that applies to 
the types of casements illustrated. Complete 
illustrations and description of all of our hard- 
ware will be found in our Casement Catalogue. 
All hardware and fittings are shipped unat- 
tached. We do not furnish expansion bolts 
or toggle bolts. 


Painting 

All casements are given a coat of rust-re- 
sisting metal primer and also a coat of dark 
gray semi-gloss enamel (both coats baked on) 
before leaving our factory. Color painting 
should be done after casements have been 
erected. We do not, in any case, recommend 
the use of full gloss enamel for final finish, as 
its hard, smooth surface usually becomes 
marred or scratched during shipping, handling 


and erecting. 


Types 

Lupton Casements are made in the following 
types:—Hinged at side to open in or out; 
vertically pivoted; horizontally pivoted, and 
projected, opening in at top or out at bottom. 
They also may be hinged at the top to swing 
out or at bottom to swing in. Top and bottom 
hinging is not generally recommended. 


Transoms may be hinged at bottom to open 
in; stationary; horizontally pivoted, or pro- 
jected to open in at top or out at bottom. 


We call your special attention to the pro- 
jected feature as applied to casements, par- 
ticularly transoms. The principle is exactly the 
same as that described under the heading of 
“Projected Sash,” page 136. Lupton Case- 
ment sections are used entirely in the con- 
struction of Projected Casements. They have 
the very desirable feature of being balanced 
and held in any position in which they are 
opened and do not require the use of chains, 
cords or special operating device to control 
them. They also permit the use of shades, 
screens and awnings. These sash may be 
arranged to open inward from the top or out- 
ward from the bottom; and sash having differ- 
ent movements may be placed in the same 
casements: for example, a casement contain- 
ing two sash could have the upper sash open 


154 


‘briefly in this general catalogue. 


outward from the bottom and the lower sash 
open inward from the top. 


All casements are built in single units. In 
openings too large for a single unit, combina- 
tions of units may be used. In such cases 
mullion bars are necessary. To obtain special 
effects in mullion and transom bar widths, 
these members may be formed from heavy 
gauge steel plate into the shape desired. This 
practice is usually followed in extremely large 
casement window construction. The general 
idea is illustrated on page 156.

Extreme care should be exercised in handling 
casements before and during erection. When 
casements leave the factory they are perfectly 
finished, fitted and squared. Careless handling 


may distort them and cause imperfect closing. 


If sash are hoisted to the upper stories of a 
building the attachment to the sash should be 
made at the center of the upper rails and never 
at a corner of the casement. 


Installation 


Lupton Casements are finely designed and 
constructed windows and should be handled 
at the building only by workmen having special 
experience with them. In order to assure that 
Lupton Casements give you results in use 
commensurate with their value, we strongly 
recommend that our contract include the 
complete installation, consisting of setting the 
sash in openings of proper size and detail to 
receive them, pointing with mastic cement, 
applying hardware and operators, and adjust- 
ing ventilating portions. We will also furnish 
glass and glaze the casements if desired. 


The subject of casement windows, their 
design, construction and application, is such 
a broad one that it can be touched upon but 
As we can 
present in these pages only a few of the more 
important features of Lupton Casements, we 
suggest that you send for a copy of our Case- 
ment Catalogue, which treats the subject in 
a comprehensive manner, before making your 
final selection and completing your plans 
and specifications. A copy will be mailed to 
you upon request.

As Steel Partitions are required to con- 
form to the walls and columns, exact infor- 
mation is needed to enable us to fill an order 
correctly. This applies to both Lupton Special 
Partition and Lupton Standard Partition. 

It is to the customer’s advantage to use 
standard dimensions, standard doors and 
standard hardware, wherever possible. 
Lupton Standard Partition is carried in 
warehouse stock; and both it and Special 
Partition can be delivered much more quickly, 
and at lower prices, where the standards 
given in the following pages are adhered to, 
than when anything special is required. 

The following information is necessary: 

1. Floor plan showing columns, walls and 

windows or mullions adjoining partitions, 
also location of doors in partitions and 


direction in which they are to swing. 
This floor plan must show dimensions, and state 
whether they are exact or approximate. Often a 
small change in layout will permit standard units 
to be used at a considerable saving in cost. 


2. Is the floor wood or masonry? 

Nature of walls (brick, plaster, etc.). 

4. Are wall surfaces, into which partitions 
run, straight or irregular up to the height 
of the partition head rail? 

If irregular, it is usually necessary to place the 
nearest mullion a short distance from the wall and 
fill the intervening space with a flanged steel filler 


plate cut to fit the wall. The same applies to 
columns.

Hardware shall be door manufacturer’s 
standard. (Specify in detail: see ““Hard- 
ware,” page 173, also illustrations, pages 
L7O t0v172.) 

Painting. All doorsshallhaveoneshop coat 
of door manufacturer’s standard paint. 


Note—Door frames should be made of 
channels with angle stops, tap-screwed in 
place. We are prepared to furnish frames. 


Frames shall have anchors built into 
masonry. 
Erection. The frames shall be plumb 


and accurately set before doors are hung. 
Doors and frames shall not be drilled for 
hinges and door checks, until after the 
doors are properly placed. 


Ordering 


Is the partition to be open or closed 
above the head rail? If closed, state 


exact distance from floor to ceiling. 
Partitions that meet the ceiling cost much more 
to make and fit than when a space (say 1 foot) is 
left. This space makes little difference in sound 
transmitted; it gives clearance for sprinkler pipes, 
etc., and it is valuable for ventilation. 


Must partitions meet window mullions? 


If so, furnish a sketch of vertical profile, so that 
a steel plate can be cut to fit the desired contour. 


Specify desired height of base plate. 


This should preferably be the standard height for 
that type of partition; but it may be desk height 
(32 inches), or some other height, at additional cost. 


Minimum door opening allowed. 
See pages 160 and 165 for standard door openings. 
Occasionally wider doors are necessary to accom- 
modate furniture or shop articles. 


Specify kind of glass desired. 
Wire grills or screens will be furnished instead 
of glass, if specified, at a suitable price. 


In the case of Standard Partition, are 


glazing angles desired? 
Glazing angles are standard only for the Special 
Partition: putty is standard for the Standard 
Partition, 


Hardware should be specified in detail. 


Our standard equipment should always be used. 
See pages 170 to172. For interior partition doors, 
locks and latches are usually unnecessary. A door 
check and pull handle are better. Where hardware 
is not specified we furnish such doors with hinges 
and pull handle, but not with door check. Out- 
side doors will be furnished, on specification, with 
cylinder locks to fit customer’s master keys. 


EUP TON SosPECTIAL PARTITION 


Lupton Special Partition 


(Patents Pending) 


Lupton Special Partition is designed for use in office and other high-grade build- 
ings. Such use requires broad surfaces in both glass and base plate, broken by the fewest 
possible lines. Strength, both in fact and in appearance, is required, plus unquestioned 
rigidity. Added to these qualities the partition must be easy to remove and rearrange. 
The standard units must be completely interchangeable. 

Lupton Special Partition is designed from the floor up for this special purpose. Its 
substantial framing, with its flat mullion surfaces and simple lines; its broad steel base 
plates and large lights; and its seamless tube doors, combine to carry out the effect of 
dignity and strength which is essential in a finely-designed office. 

The ready removal so necessary in office partitions is made possible by the ingenious 
design of mullions and head rails, which permits them to be taken apart merely by 
removing a few bolts. Interchangeability is secured by making all units, including door 
units, of standard widths and heights: hence a partition or door may be relocated 
whenever changes in the floor layout make that desirable. The partitions may extend 
part or all the way to the ceiling. 

Standard base plates are 48 inches high from the floor. The space above is filled with 
large lights of any glass desired, or with wire screens. The mullions are attached to the 
floor by neat and inconspicuous standards.

LUPTON oTAN DARD PARTITION 


Lupton Standard Partition 


Lupton Standard Partition is intended for use in warehouses, mills, factories, garages 
and industrial buildings generally. It is as carefully planned for this class of service 
as Lupton Special Partition is for office uses. 

Although made up chiefly from steel sash members, Lupton Standard Partition gives 
nowhere the effect of a transplanted window. The mullions are individual in character; 
the sash frames are set into and concealed by the mullions; and both the glass lights and the 
steel base plates are so much larger than the lights of ordinary factory sash that their 
appearance suggests no comparison. ‘Timekeepers’ and foremen’s offices, stockrooms, and 
the like, enclosed in Lupton Standard Partition, present as thoroughly appropriate and 
dignified an aspect, and one as free from any suggestion of makeshift, as the most finely 
appointed office does when equipped with Lupton Special Partition. 

Lupton Standard Partition may be removed and relocated without damage. Units be- 
tween doors are made of standard interchangeable widths,,and the doors likewise are in- 
terchangeable. Door units cannot be interchanged with units between doors, but the 
latter units can readily be moved to accommodate changes in location. 

Lupton Standard Partition is carried in stock at our principal warehouses. 


Each unit of this type of partition forms a Mullions and Head Rails

The intermediate mullions are specially In the high partition every mullion runs to 


rolled H beams of proper size to suit the sash 
frame channels. Three and four-way mullions 
are made by spot welding formed steel channels 
to the H beam flanges. Door frames are 
similarly made from plate angles and Z bars, 
spot welded and bolted. 

The corner mullions are made of two formed 
angle bars clamped to the sash frame. Details

each light, and puttied. Glazing angles are 
used only if specified and at an additional cost.

The three views on this page show a Lupton Seamless Tube Door equipped 
with Von Duprin Panic Lock. This lock is intended for exterior doors of schools, 
theatres, office buildings, libraries and public buildings generally. It is arranged 
to be locked against entrance from outside, but is at all times free to open from the 
inside (whether locked or unlocked), by pressure on the horizontal inside brass bar. 
There is no jamb latch. Instead, there are top and bottom spring latches, which 
are released from the outside by a knob and cylinder lock, and from the inside by 
the horizontal bar. 


When the latches are withdrawn by pressing the bar, they stay thus till released 
by a catch connected to the bottom latch. 


All exposed parts are polished brass. Any standard cylinder lock can be used. If 
not otherwise specified a Sargent lock will be used.

Lupton Seamless Tube Doors 


These doors are used for inside and outside doors of factories, power houses, warehouses 
and industrial plants generally. Their great strength makes them especially suited to 
freight entrances, car and locomotive shops and the like. 

They have a one-piece framework of rectangular seamless steel tube. All joints 
are oxy-acetylene welded. This construction gives great strength and rigidity, and 
leaves no openings through which moisture could enter to cause internal corrosion.

Lupton Standard Doors 


Lupton Standard Doors are intended for use 
in factories, foundries, warehouses and similar 
buildings, where a strong and well-made door 
is desired but the exceptional strength of 
Lupton Seamless Tube doors 1s not necessary. 


These doors are of built-up construction, 
heavy materials being used and vital points 
being welded. They give excellent satisfaction 
in sizes up to the recommended maximum of 
4 by 8 feet per leaf for swinging doors, and 8 
by 10 feet for sliding doors. For all uses they 
are far superior to doors of wood or light gauge 
sheet metal. They are in every way equal to 
current practice in built-up steel doors. 


The stiles are composed of No. 14 gauge 
steel plate formed into deep channels, naitred 
at the corners. The mitred joints are welded 
solid by the oxy-acetylene process, making a 
rigid construction with smooth exterior finish. 


The channel stiles are through-bolted to 
steel sash members which form part of the 
framework holding the glass and base panel. 
The remainder of the framework is composed 
of standard steel sash muntins assembled in 
the usual way. 


The base panels are No. 20 gauge plate. 
Instead of being held by putty, they are 


flanged and riveted to the sash members. 


Lupton Standard Doors are carried in stock 
in the size used with Lupton Standard Parti- 
tion, namely, 3 ft. wide and 7 ft. 732 in. high. 
Other sizes are made to order up to the limits 
mentioned above. 


Standard hardware for swinging doors con- 
sists of a malleable pull handle and two ball- 
bearing butt hinges. Door checks, top and 
bottom bolts, cylinder locks and lever handle 
latches will be furnished at an additional price 
and only when specified in estimate and order. 
See pages 170 to 172 for hardware items recom- 
mended for use in this manner. 


The corners of Lupton Standard Doors are mitred and welded 
by oxy-acetylene process, giving rigidity and permanent 
security against sagging.

plate, with or without imposts, to fit any type of 
interior wall. 

Corners are accurately mitred and all joints 
securely and neatly welded. The central 
stop of each member may be varied in width to 
suit the thickness of the wall. Height and width 
of frames, and location of imposts, are made to

are used, in connection with reinforcing plates in 
the frames. 

Frames are shipped assembled and crated, with 
ends braced by angle bars which are left in the 
floor concrete (see dotted lines). Walls are left un- 
finished till frames have been set, and anchor 
plates (furnished by us) are built into them to 
locate frames. 


LUPTON 
ROLLED STEEL SKYLIGHT 


(Patented by Joah Brogden) 


Lupton Rolled Steel Skylight is especially adapted to conditions of unusual severity, 
such as vibration, wide range of temperatures, and inaccessibility for frequent painting. 

By its patented construction, breakage of glass due to expansion and contraction and to 
vibration is eliminated; also leakage due to drying of putty, rapid deterioration by cor- 
rosion, and collection of dust by condensation gutters. The principal causes of glass 
breakage are vibration, especially with skylight bars of light cross section, and the expan- 
sion and contraction of glass rigidly held in putty or clamped between metal holders. In 
Lupton Skylight the glass is supported between flexible strands of specially saturated 
fibre. These not only permit free expansion and contraction, but eliminate leakage as 
well, since no putty is used. 

All metal parts directly exposed to weather are copper and brass. Galvanized copper- 
bearing steel may be used instead of copper, at a corresponding price. 

Lupton Skylight has no cross bars. Where these would ordinarily occur, the bars and 
caps are offset to permit a lap of three inches in the lights. 

Erection of Lupton Skylight involves no cutting and fitting. All members are cut to 
exact size, the bars and caps are offset at the factory, and all parts are shipped ready for 
assembling. Erection can be done by ordinary mechanics.

CORRUGATED WIRE GLASS 


Because of its unusual strength Corrugated Wire Glass does not require the support and 


protection of a specially constructed frame work. It is laid on steel or wood purlins in the 
same manner as corrugated iron, except that strips of asphalt paper are first applied to 


the purlins. 


Combining the qualities both of a roof covering and a skylight, Corrugated 


Wire Glass may be used as a complete roof from ridge to eaves; or it may be laid over 
openings of desired sizes in direct connection with any roofing material; or on a curb 


raised above the roof surface. 

The corrugations widely diffuse entering 
light rays and eliminate all glare. The 
glass is laid with the smooth surface on 
the weather side, and rain washing over 
the corrugations keeps it clean. As a fire 
retardant, Corrugated Wire Glass possesses 
all the qualities of wire glass in flat 
sheets. 

Corrugated Wire Glass is a full 4" thick 
and weighs about five pounds per square 
foot. Standard lights are 2734" wide by 
42 and 63 long. Corrugations are 2.52’ 
across and 3%” deep. 

When so desired, we will furnish cover 
caps for joining lights, necessary bolts, 
washers, clips, asphalt paper strips for 
glass rests, ridge roll and other sheet metal 
accessories.

LUPTON STEEL SHELVING 


Lupton Steel Shelving incorporates fundamental qualities of design and construction 
which make its first cost on any basis of comparison always an economy, and which give 
it increasing investment value with each expansion or rearrangement of stock, periodically _ 
necessary, inevery growing concern. ‘This applies to old plants now using wood shelving, 
as well as to new plants for which the most efficient storage equipment is wanted. 


Bin Type 

This type of shelving, which is most commonly used, is open only at the front. The 
front edges of the sides are formed around flat reinforcing bars of high carbon steel, 
resulting in a T-bar construction with ample strength to support 
the shelf load, and to withstand rough usage. The back edges of 
side uprights are flanged and bolted through the back upright. 


The front edge of the shelves is reinforced by being formed 
tightly around a specially rolled channel bar, whose ends are bent 
at right angles and bolted to the side uprights. At the sides and 
back the shelves are flanged downward and bolted to the uprights. 


Rack Type 


This type is usually open for access from all four sides. The 
uprights are T-bars, hot rolled from medium carbon steel, and are 
punched for attaching the shelves. 


Shelves for this type have both the front 
and back edges formed around the channel 
bar reinforcement described above, and the 


ends of the channels are bent at right angles Lupton Rack Type

Label Holders— These may be fastened either to shelves or to bin fronts. 

Counter Extensions—They give additional storage space and provide easy means of 
reaching upper shelves without using a ladder. 

Lupton Steel Shelving is attractively finished in velvet green enamel, oven baked. 
Unless otherwise specified, it is shipped knocked-down. All necessary bolts and nuts 
are provided.

LUPTON STEEL BOOKSTACKS 


Lupton Bookstacks are designed to meet the requirements of large and small institu- 
tional and public libraries. They combine effective storage space and accessibility with 
a highly attractive appearance. The stacks are made for single floor and for multiple decks. 


The vertical members are double H beam columns, which directly carry the shelves and 
receive the framing for deck floors, if any. These columns are notched for vertical shelf 
adjustment on centers of 
1%" and provide a four 
point bearing for each 
shelf. The usual spacing 
of the columns is on cen- 
ters of 4’ across the aisles 
and 3 parallels withe the 
aisles. Standard height 
is 7’ from floor to floor.

WALDMIRE LOUVER 


(Patented) 


Construction 
Waldmire Louvers are made of suitably 
formed slats which are vertically spaced 6 


inches on centers and set in continuous lines 
entirely outside of all supports. The slats are 
made in a standard length of 10 feet and are 
given a lapped joint of 11% inches. This con- 
struction eliminates exterior posts, panels and 
The shape of the 
louver slats with a horizontal flange at the top 
assures least opportunity for entrance of rain 
and snow. Unless otherwise specified, Waldmire 
Louvers are made of 22 gauge galvanized Key- 
stone Metal, a copper bearing metal which 


all soldered connections. 


shows remarkable resistance to the action of 
rust and fumes. 


Waldmire Siding 
For tobacco barns, drying sheds or other 
buildings where continuous ventilation is re- 
quired, we furnish Waldmire Siding of the same 
construction as the louvers but made for ver- 
tical spacing of 12 inches on centers.

or steel, should be set on centers of §914 inches,

Louvers are fastened to woodwork by 


port of louvers or siding, but will submit draw- 
ings giving complete details and punching

Erection

erect Waldmire Louvers and Siding with un- 
skilled labor; no soldering or any sheet metal 
worker’s tools are necessary. 


. Comparison 


For practicability of construction, compare 
Waldmire Louvers and Siding, set in continu- 
ous lines outside of all structural work and 
without panel posts, riveted or soldered con- 
nections, with paneled construction, soldered 
or riveted to posts. For quality of material, 
compare 22 gauge galvanized Keystone Metal 
with lighter gauge galvanized steel. [For com- 
plete cost in place, compare the cost of erecting 
by unskilled labor with the cost of highly paid 


sheet metal workers.

We do not include any head or cornice mould- 
ings or sill aprons unless specifically called for.
